What Are IP Addresses & How Do They Work?
Definition & Purpose of IP Addresses
An IP address is like a home address for your device on the internet. It’s a unique identifier made up of numbers that allows your device to communicate with other devices and access information online.
IP stands for Internet Protocol, which is the set of rules governing how data is transferred across the internet or local networks.
So in simple terms, an IP address is the address your device needs to participate on the internet. Think of it like sending a letter – you need to include the correct mailing address or it won’t reach its destination.
The main purposes of IP addresses are:
- Identification – An IP address identifies a specific device on a network. Without it, devices would not be able to distinguish each other on the internet.
- Routing – IP addresses allow data packets to be routed between devices. The source and destination IP addresses help traffic get to the right place.
- Geolocation – While not 100% precise, IP addresses provide a general sense of a device’s geographical location. This is helpful for content localization.
- Security – IP addresses allow network administrators to control access and implement security measures based on known IP addresses.
So in summary, IP addresses act like unique digital postal addresses to identify devices and enable routing and security across the internet.
Types of IP Addresses (IPv4 vs IPv6, Static vs Dynamic)
There are a couple of different ways IP addresses are classified:
IPv4 vs. IPv6
The two core types of IP addresses are IPv4 and IPv6. Here’s a quick rundown:
- IPv4 (Internet Protocol version 4) – This is the older, 32-bit address scheme. It consists of 4 sets of digits separated by periods, like 192.168.1.10. IPv4 allows for around 4 billion unique addresses.
- IPv6 (Internet Protocol version 6) – The newer 128-bit address format. It’s written in hexadecimal notation and looks something like 3ffe:1900:4545:3:200:f8ff:fe21:67cf. The much larger address space of IPv6 (2^128) solves IPv4 exhaustion.
IPv6 was created to accommodate the rapid growth of the internet and connected devices. While both addressing schemes function similarly, IPv6 provides a massively larger pool of available addresses.
Static vs. Dynamic
IP addresses can also be static or dynamic:
- Static IP Addresses – These do not change and are persistent. They are manually configured by network admins. Static IPs allow devices to be reliably identified on networks.
- Dynamic IP Addresses – These IP addresses automatically change periodically, usually assigned by DHCP servers. This allows IP addresses to be reused and devices to get new network configurations. Home networks usually use dynamic IPs.
So in summary – IPv4 vs IPv6 refers to the IP address formats, while static vs dynamic relates to whether the IP address changes. Both schemes are widely used today for different purposes.
How IP Addresses Map to Domain Names via DNS
So we know IP addresses uniquely identify network devices. But human-readable domain names are what we actually type in to access websites and resources.
The Domain Name System (DNS) handles translating domains into their corresponding IP addresses.
When you type a domain name into your browser, a DNS lookup takes place:
- Your browser checks its DNS cache for any existing record of the domain’s IP.
- If no record is found, your computer makes a recursive DNS query through your Internet Service Provider to find the IP.
- The top-level DNS servers redirect the query down through the DNS hierarchy until the IP address is found.
- Once the IP is located, the address is returned to the original requester and cached for future lookups.
So DNS acts like an address directory, allowing us to use memorable domain names instead of hard-to-remember IP strings.
Fun fact: The very first DNS entry mapping a domain name to an IP address was for Symbolics.com in 1985, which pointed to IP address 192.0.2.153.
This domain/IP mapping is a fundamental part of how browsing the internet works. DNS servers around the world maintain these databases that convert domains into routable IP addresses behind the scenes.
So in summary, DNS is the essential service that matches domains with their corresponding IPs, making the internet and websites accessible by users. It’s the silent helper converting those strings of numbers into human-friendly websites for us to visit.
Dedicated IP Addresses vs Shared IP Addresses
Now that we’ve covered the basics of what an IP address is, let’s look at the two main types of IP addresses used for hosting websites and sending email – dedicated and shared.
What is a Dedicated IP Address?
A dedicated IP address, as the name suggests, is an IP address that is assigned to only one user or domain.
For example, if you register the domain www.mybusiness.com, your hosting provider could assign it the dedicated IP address of 192.0.2.1. That IP would resolve only to your domain and couldn’t be used by any other websites.
Some key things to know about dedicated IPs:
- They are more expensive since the cost isn’t shared with other users.
- You have full control and ownership of the IP address and its reputation.
- There is no risk of another website’s behavior impacting your IP.
- It’s perceived as more secure and professional to have your own dedicated IP.
- You don’t have to share resources like bandwidth and CPU with other sites.
Dedicated IPs are commonly used for mission-critical business applications, email servers sending high volumes of email, and enterprise-level hosting with full administrative access.
What is a Shared IP Address?
In contrast to dedicated IPs, a shared IP address is used by multiple users/domains.
For example, the websites www.site1.com, www.site2.com, and www.site3.com could all share the same IP address of 192.0.2.2.
Some key things to know about shared IPs:
- They are extremely cost-effective since the IP address cost is shared.
- You don’t have full ownership of the IP – it’s shared with other users.
- There is some risk that other users could impact the IP’s reputation.
- Shared IPs are commonplace and used by many major websites.
- Resources like bandwidth must be shared between all users of the IP.
Shared IPs work well for small websites just getting started, low-volume email sending, and basic website hosting needs. They keep costs down by sharing IP expenses across customers.
Key Differences Between Dedicated and Shared IP Addresses
To recap, here are the major differences between dedicated and shared IP addresses for hosting and email:
| Dedicated IP Address | Shared IP Address |
| Assigned to only one user/domain | Used by multiple users/domains |
| More expensive | Extremely cost-effective |
| Full ownership and control | Shared ownership and control |
| No risk of IP reputation issues from other users | Some risk of usage problems from other users impacting reputation |
| Perceived as more professional and secure | Very commonplace, used by many major sites |
| No resource sharing – dedicated bandwidth, CPUs, etc | Resources like bandwidth shared between users |
| Best for mission-critical apps, large email volumes, full admin access | Great for low-volume emails, small sites just starting out |
The choice between using a dedicated or shared IP really depends on your specific needs and priorities.
Dedicated IPs provide full control and ownership at a higher cost, while shared IPs offer an affordable way to share an IP between many users. Evaluate whether your application’s traffic levels, security needs, and hosting requirements warrant a dedicated address vs sharing resources cost-effectively on a shared IP.
When Should You Use a Dedicated IP Address?
Now that we’ve explored the differences between dedicated and shared IP addresses, let’s dive into some of the specific use cases where using a dedicated IP makes sense.
Sending High Volume Email
One of the most common reasons businesses purchase dedicated IPs is for sending large volumes of email.
Why does high volume email favor dedicated IPs? There are a few reasons:
Deliverability and Inbox Placement
Email service providers carefully monitor the send reputation of IP addresses. If an IP is associated with a lot of spam or complaints, ISPs like Gmail will be more aggressive about filtering its emails to spam.
When you send email from a shared IP, the sending reputation is shared by all users of that IP. So if one user abuses email sending practices, it hurts everyone.
With a dedicated IP, you have full control over maintaining your sender reputation. As long as your own email practices are sound, you won’t have issues with blacklists or filters flagging your emails as spam.
Ownership and Flexibility
Owning your own dedicated IP for email allows you to seamlessly migrate between email service providers without having to rebuild IP reputation. It also allows greater flexibility to make changes as your email program evolves.
Security and Privacy
While shared IPs work great for small volume email sending, very high email volumes originating from a shared IP can sometimes attract unwanted attention from bad actors. A dedicated IP helps keep your email sending program isolated and less susceptible to security and privacy issues.
So in summary – dedicated IPs give high volume email senders greater control, deliverability, security, and flexibility.
How many emails per month should you consider a dedicated IP?
There’s no hard and fast rule, and it depends on your specific sending patterns and risk tolerance. But in general:
- Under 50,000 emails per month – A shared IP is probably sufficient.
- 50,000 to 500,000 emails per month – Time to consider a dedicated IP.
- Over 500,000 emails per month – A dedicated IP is strongly advised.
Work with your email service provider to evaluate your monthly send volumes and determine if a dedicated IP makes sense.
Using Your Own SSL Certificate
SSL (Secure Sockets Layer) certificates encrypt traffic between a website and visitors’ browsers, enabling secure HTTPS connections.
In the past, using your own SSL certificate required purchasing a dedicated IP address. However, a technology called SNI (Server Name Indication) now allows multiple SSL certs to be hosted on the same shared IP.
But there are still cases where a dedicated IP is required for custom SSL certificates:
Legacy Systems
A very small percentage of outdated systems don’t support SNI. For these legacy configurations, a dedicated IP is needed to use custom SSL certificates.
Max Security Environments
Some high security organizations may mandate dedicated IPs when using custom SSL certificates. This provides an added layer of isolation and security.
Full Control
Big enterprises that want maximum control over their web infrastructure sometimes still opt for dedicated IPs to have full flexibility over SSL certificates and configuration.
So in summary – you only need a dedicated IP for your SSL certificate in rare legacy setups without SNI support, highly secure environments, or when full admin control is required.
For nearly all regular websites and apps, shared IPs can handle SSL certificates just fine nowadays.
Advanced Security Concerns
Due to the nature of shared resources, shared IPs inherently provide less isolation from a security standpoint. While attacks are rare, vulnerabilities in one website or application on a shared server can potentially impact others.
Some situations where dedicated IPs may be advised for increased security:
- Websites handling highly sensitive data (health records, financial data, etc.)
- Companies dealing with intellectual property theft risks
- Organizations operating under strict regulatory compliance
- Websites subject to frequent targeted attacks like DDoS
- Networks with legacy hardware and software vulnerabilities
The extra security “sandbox” provided by dedicated IPs adds an additional layer of protection for sites and applications operating under high-risk scenarios.
Of course, robust cybersecurity practices are still crucial regardless of whether a dedicated or shared IP is used. But the added isolation of dedicated IPs may appeal for organizations with rigorous security requirements.
Enterprise-Level Hosting Requirements
Larger organizations with IT teams that need granular control over network infrastructure frequently make use of dedicated IPs.
Why dedicated IPs for enterprise hosting?
- Ability to customize IP-based firewall rules.
- Segment internal applications by IP addresses.
- Make networking changes without affecting other customers.
- Integrate with other dedicated IPs from a different provider.
- Ability to use non-standard ports restricted on shared IPs.
- More flexibility for advanced traffic management and routing.
- Isolation of critical apps – If one app/site fails, others are not affected.
- Internal branding, accounting and reporting purposes.
So in summary, while shared IPs work for most website hosting needs nowadays, large organizations running complex or mission-critical sites may still benefit from the flexibility of dedicated IPs.
The key is understanding your specific requirements and weighing the extra control against the increased costs.
Benefits and Drawbacks of Dedicated IP Addresses
Dedicated IP addresses come with both advantages and disadvantages compared to shared IPs. Let’s explore the key benefits and drawbacks of using dedicated IPs for email and web hosting.
Benefits of Dedicated IPs for Email & Hosting
Full Ownership and Control
One of the biggest benefits of a dedicated IP is that you have complete control over the IP’s usage and reputation. You don’t have to worry about other users impacting your deliverability or security.
Flexibility
Dedicated IPs provide more flexibility to implement custom firewall policies, traffic routing rules, and make infrastructure changes without affecting other customers on shared servers.
Privacy and Security
Dedicated IPs help isolate your websites and applications from other users for improved privacy and security. You also gain more options for implementing robust cybersecurity rules and policies.
With high-volume email sending, dedicated IPs ensure consistent sender reputation, avoiding issues that can occur when sharing an IP with other bulk email senders.
Professionalism and Credibility
Dedicated IPs project an image of professionalism, reliability and credibility for businesses and established organizations. Customers feel their data is in safe hands.
No Resource Sharing
With a dedicated IP, you don’t have to share bandwidth, CPUs, disk space, or other finite resources with hundreds of other users on a shared server.
So in summary, dedicated IPs provide ownership, control, flexibility, security, deliverability, professionalism, and guaranteed resources for organizations with rigorous needs.
Drawbacks and Challenges of Dedicated IPs
However, dedicated IPs also come with some downsides:
Higher Cost
Dedicated IPs are more expensive than shared IPs since you are shouldering the entire cost rather than splitting it among many users. They also have higher maintenance overhead.
Overkill for Smaller Websites
The vast majority of smaller sites will not benefit enough from a dedicated IP to justify the additional expenses. A shared IP works great for most low to medium traffic sites.
No Sharing of Resources
While not sharing resources can be a benefit, it also means you alone are responsible for managing the IP’s usage and limits. You don’t have the cushion of a shared pool.
Lack of Email Sending History
Newly allocated dedicated IPs start with a blank reputation when it comes to email sending. It takes diligent work to build deliverability over time.
Security Responsibility
You take on full duty for protecting and securing a dedicated IP. Any oversights or vulnerabilities could have dire consequences.
Limited Provider Options
Not all hosting companies offer dedicated IPs. The additional support and infrastructure requirements mean fewer providers accommodate them.
In summary, while dedicated IPs provide greater control and resources, they also entail higher costs, more responsibility, no sharing of burdens, and greater effort to achieve good email deliverability and security.
When Does a Shared IP Address Make Sense?
While dedicated IPs have their place, shared IP addresses are still a smart choice for many situations. Let’s explore some examples where opting for a shared IP over dedicated makes the most sense.
New Websites Just Starting Out
For new websites just getting off the ground, a shared IP is the clear choice. Here are some of the key reasons why:
Cost Savings
When starting a brand new site, keeping costs down is critical. Shared IPs allow you to split the price with other users, making website hosting extremely affordable.
Quick and Easy Setup
With shared hosting, you can get your site up and running almost instantly. You don’t have to spend time requesting and configuring your own dedicated IP.
Leverage Existing Reputation
New IPs without a sending history are often treated suspiciously. But on a shared IP, you benefit from the positive reputation of established sites also using the shared space. This helps ensure your new site avoids extra scrutiny.
Share Resources
Brand new sites typically have low visitor traffic. On a shared server, you seamlessly scale up and down with the cushion of resources from other sites on the IP as needed.
Few Security Concerns
When your site is brand new with little to no traffic, you have less to worry about in regards to security vulnerabilities. Shared hosting is plenty secure for most starter sites.
So in summary, new and low-traffic websites see very little advantage in dedicating the additional effort and cost needed for a dedicated IP address. Stick with shared.
Small Business Websites
Typically, small business websites (such as local restaurants, boutiques, professional services, etc.) will find that a shared IP provides everything they need:
- Cost effective and easy to manage
- Fast and seamless setup
- Ability to scale up if the business takes off
- Minimal security concerns
- Avoid overspending on unnecessary dedicated resources
Really, the only instance a small business site would require a dedicated IP is if they expect extremely high target traffic right off the bat or have stringent security requirements.
But in most cases, small business owners are better off keeping their costs down and sticking with a shared IP unless their hosting needs grow substantially.
Low-Volume Email Sending
We previously discussed how dedicated IPs make sense for very high email volumes. But on the flip side, here are some reasons shared IPs work well for lower volume email sending:
Cost
If you are only sending occasional emails to customers or a small subscriber list, paying for a dedicated IP would quickly eat into any budget. Shared IPs allow maximum savings for low-volume senders.
Deliverability
Spam filters are especially suspicious of brand new IPs with sparse sending history. On shared IPs, your limited emails will blend in with the volumes of others, avoiding extra scrutiny.
Ease of Management
With such a low volume of email, you likely don’t want the hassle of manually managing all facets of your IP’s deliverability and reputation. Let your shared IP provider handle that.
Flexibility
If you eventually scale up your email marketing down the road, it’s easy to upgrade to a dedicated IP. But shared IPs provide flexibility to send limited emails affordably.
So the consensus is that modest email sending of under 50,000 messages per month does not warrant the expense of dedicating an entire IP address. Stick with shared.
Basic SSL Encryption Needs
In the past, dedicated IPs were required to use custom SSL certificates. But as mentioned earlier, a technology called SNI changed this.
Thanks to SNI, shared IP addresses can now support SSL encryption for the vast majority of modern sites:
- Shared IPs work seamlessly with free SSL certificates from providers like Let’s Encrypt.
- Any website visitor using a reasonably modern browser will have no issues with SSL on a shared IP.
- No need to pay extra for a dedicated IP solely for basic SSL certificate needs.
- The tiny fraction of users on outdated systems without SNI support aren’t worth catering to.
So in summary, requiring a dedicated IP address “just” for SSL certificate use is outdated advice. Shared IPs now provide all the functionality nearly all sites need for encrypting traffic via HTTPS.
Shared IP Considerations and Best Practices
Shared IPs provide an affordable and easy solution for many website hosting scenarios. But there are some best practices to follow and considerations to keep in mind to ensure smooth operations on a shared IP.
How to Choose a High-Quality Shared IP Host
Not all shared hosting providers are equal in terms of the infrastructure, network, and IP reputation they offer. Here are some tips for choosing a high-quality host for your shared IP:
Look for Technological Safeguards
Choose a host that uses advanced technology like containerization or virtual machines to isolate accounts from each other even while sharing server resources. This prevents issues with one account bringing down or impacting others.
Ask About Uptime and Reliability
Inquire about the provider’s historical server uptime and reliability. The robustness of their network and data centers will directly impact your website’s performance and availability.
Research Their IP Reputation
Do some digging to understand the reputation of the provider’s shared IP ranges. Are they known for spam or malicious traffic? Or do major ISPs highly trust their IPs?
Understand the Shared Server Setup
Ask questions to learn about how the provider clusters accounts on shared IPs. Do they group similar site types together? What is the max number of accounts per IP?
Look for Proactive Security
Choose a provider that takes spam filtering, DDoS prevention, firewalls, and malicious activity monitoring seriously to protect their shared infrastructure.
Check Reviews and Talk to Customers
Take time to read through independent reviews and hopefully chat with current customers about their experiences with support, uptime, and deliverability.
Tips to Maintain Your Reputation on Shared IPs
Once on a shared IP, you’ll want to be a good neighbor to other users and avoid damaging the IP’s reputation. Here are some tips:
Monitor Your Own Traffic
Keep a close eye on your website analytics and server logs to catch any suspicious spikes in traffic that could indicate an issue or attack.
Practice Good Security Hygiene
Follow all recommended security best practices like keeping software updated, using strong passwords, monitoring for vulnerabilities, etc.
Carefully Vet Any Mail Lists
Scrub any email lists you upload for old, inactive addresses that could cause deliverability issues like bounces.
Send Emails in Moderation
Avoid blasting out millions of emails per day, which could trigger spam red flags. Build volume gradually over time.
Avoid Shady Traffic Sources
Be cautious of low-quality ads or traffic sources that could send spammy clicks and hurt your site’s reputation.
Communicate With Your Provider
Let your shared hosting provider know about any major expected traffic spikes or email campaigns so they can accommodate.
Remember, exercising caution and communicating with your provider is key to sharing an IP responsibly. Together, you can maintain a healthy reputation.
Migrating IP Addresses and Their Impact on SEO
When it comes time to switch hosting providers, a common question that comes up is how changing IP addresses affects SEO and website rankings. Let’s explore some specifics around migrating IPs.
Can You Transfer a Dedicated IP to a New Host?
If you currently have a dedicated IP address, you might be wondering if you can simply transfer it to a new hosting company when you switch providers.
Unfortunately, dedicated IP addresses cannot be migrated between hosts. Here’s why:
When you first purchased your dedicated IP, it was assigned to your account and configured to point to your domain on your hosting provider’s servers.
That IP has essentially become tied to your account and their systems. It relies on their DNS records and routing rules in order to resolve to your domain.
So if you were to try to transfer it to a new provider, the IP would essentially break once it was no longer pointing to your site on the original host’s network.
Think of it like building a house, then trying to physically relocate the entire structure to a new neighborhood. The connections to utilities and services just won’t carry over.
Now, when you switch providers, you can bring your domain name with you and get a new dedicated IP from the new host. But you’ll be starting fresh in terms of configuring the IP address and establishing reputation.
The good news is, dedicated IP reputation is associated with a domain, so your sender reputation will move over to the new IP as long as the domain remains constant. But you’ll essentially be getting a fresh start IP-wise.
Does Changing IP Addresses Affect Rankings?
So how does getting a new IP address, whether dedicated or shared, impact SEO when you switch hosts?
The short answer is – it doesn’t. Changing IP addresses does not directly harm your SEO or rankings.
Google has confirmed numerous times that switching IP addresses is not something they consider a ranking factor. As long as your domain name remains the same, any IP changes will not negatively impact rankings.
Here are a few things to keep in mind regarding IPs and SEO:
- Google expects sites to change IPs occasionally due to migrations, new hosts, security additions, etc. They understand how the web works.
- The algorithms today are extremely advanced. They evaluate domains based on a wide range of quality signals – not just IPs.
- Sites worry about a temporary blip in traffic around a DNS change, but this quickly rebounds after a few days once DNS propagates.
- Major sites change IPs constantly without issue. Just think – even Google migrates their own infrastructure all the time.
- Simply monitoring rankings is flawed – many other factors like search volume/competition determine rankings over time.
So in summary, while you’ll certainly want to plan your migration carefully and minimize any downtime, you do not need to worry about IP address changes hurting your SEO or keyword rankings. It is a normal part of operating websites.
The key is focusing on migrating your site properly and redirecting any old domains/URLs to the new site. Follow SEO best practices through the transition and you’ll be fine. Your search engine visibility and rankings will recover quickly after any temporary DNS hiccups.
Purchasing and Managing Dedicated IP Addresses
If you’ve determined that a dedicated IP address fits your needs, here are some tips for purchasing your own dedicated IPs as well as managing them effectively.
How Much Does a Dedicated IP Address Cost?
Pricing for a dedicated IP address can vary quite a bit depending on your web host and geographic location. Some ranges to expect:
- $5 – $20 per month for a dedicated IP from many mainstream web hosting companies.
- $20 – $50+ per month for IPs from specialized email providers and IT vendors.
- $50 – $100+ per month for premium dedicated IPs from enterprise-grade providers.
So in general, you’ll almost always pay more for a dedicated IP over a shared one. But hosts offering dirt cheap dedicated IPs may cut corners, so avoid prices that seem unrealistic.
When comparing options, look for providers that can offer dedicated IPs in your target region or country to minimize latency. North American and EU IPs tend to be cheaper than Asia or South America.
Also consider requesting a /29 IP subnet, which contains 6 usable IPs. The cost increase is usually minimal but provides some room to scale.
Where to Obtain Dedicated IP Addresses
There are a few options for obtaining dedicated IP addresses:
Your Web Host
Many standard web hosts offer dedicated IPs either bundled with higher tiers of hosting plans or as add-ons to basic shared hosting packages.
Email Service Providers
Services focused specifically on email delivery will also lease dedicated IPs so you can send email from your owned IP address.
Cloud Hosting Providers
Companies like AWS, GCP, and Azure offer dedicated IPs you can use when configuring VM server instances on their cloud platforms.
Internet Service Providers
Some business-class ISPs provide dedicated IPs to customers. This option removes any intermediary hosts but requires you to manage your own server.
Speciality IP Marketplaces
There are also specialty IP leasing companies focused just on procuring and managing dedicated IPs for lease.
So shop around to find a provider that offers competitively priced dedicated IPs in the regions you need.
Tips for Configuring and Managing Dedicated IPs
Once you purchase your own dedicated IP addresses, you’ll want to take steps to configure and manage them optimally:
- Ensure the IP is fully isolated from any other accounts or users on your host.
- Configure reverse DNS properly to improve deliverability and avoid spam filters.
- Set up firewall policies, access controls, and security rules specific to your IP.
- Document all technical details related to routing, DNS, subfolders, etc.
- Monitor usage closely and expand your IP allocation if you’re exceeding capacity.
- Keep careful records of IP reputation, including any blocks or spam listings.
- Follow email best practices for dedicated IPs as you build deliverability.
- Periodically audit configuration and security settings for vulnerabilities.
Owning dedicated IPs gives you greater power but also greater responsibility. Take management of your IPs seriously to maximize the benefits while avoiding pitfalls.
Using Proxies and VPNs with Dedicated & Shared IPs
In addition to choosing between a dedicated or shared IP, some users also want to know whether using a proxy service or VPN is recommended. Let’s explore how proxies and VPNs can enhance security and privacy for both IP configurations.
Benefits of Proxies and VPNs for Security
Proxies and Virtual Private Networks (VPNs) work by masking your real IP address and rerouting your traffic through an intermediary server. This provides some great security and privacy benefits:
Hide Origin IP Address
By proxying or VPNing your traffic, external parties won’t see your true origin IP, only the proxy/VPN IP. This helps obscure your infrastructure details.
Prevent Attacks
Hackers can’t directly attack your origin IP address if it’s hidden behind a proxy or VPN. This adds a layer of protection.
Encrypt Traffic
Proxies and VPNs encrypt your traffic so that data can’t be intercepted and read during transit between networks.
Bypass Geographic Blocks
Certain sites block traffic from certain physical regions. But proxies and VPNs allow you to appear to connect from a different location.
Avoid Local Surveillance
Proxies and VPNs prevent your local ISP or network from monitoring and logging all sites you visit and traffic you send.
Improve Anonymity
By anonymizing your IP and traffic, proxies/VPNs make it much harder for sites or data brokers to profile your browsing behavior.
So for the greatest privacy and protection while web hosting or sending email, utilizing a proxy or VPN in addition to your IPs is a great idea.
When Proxies and VPNs Are Not Needed
However, proxies and VPNs certainly aren’t mandatory for every website, and there are some cases where they provide minimal benefit:
Personal and Small Business Sites
If you’re just running a basic website for your own purposes or very small business needs, proxies likely provide little advantage. Shared IPs are plenty secure.
Sites Not Handling Sensitive Data
Websites that don’t process private user information probably don’t need to anonymize traffic with proxies. Public sites have little to hide.
Internal Business Applications
Apps and sites behind a company firewall, only accessible internally to employees, have no need for extra proxy security.
Disposable Sites
Short-lived sites like basic coming-soon pages don’t require encrypting traffic and hiding origin IPs.
Test and Development Environments
No need to proxy dev or staging sites not exposed to the public web. Add security layers when promoting to production.
Cloud-Hosted Microservices
Micro-sites and functionality isolated in cloud serverless environments gain minimal hardening from proxies/VPNs. Their attack surface is already minimized.
So in summary, while proxies and VPNs are great additional privacy tools, they aren’t always necessary depending on the purpose of your site and how you’re hosting it. Assess their benefits for your specific goals.
Some good questions to ask are:
- Is all my traffic already encrypted via HTTPS?
- Am I passing any sensitive user data?
- Is my origin infrastructure hidden from public view?
- Am I concerned about government or ISP surveillance?
If the answer is yes to any of the above, a proxy or VPN service could be a wise additional investment for web security.
Final Tips for Choosing the Right IP Setup
If you’ve made it this far, hopefully you now have a solid understanding of the key factors and tradeoffs between using dedicated IPs and shared IPs for hosting your websites and sending email.
To wrap up, here are some final tips to help you decide on the best IP configuration for your needs:
Audit Your Network Usage
Take stock of the number of websites you host, monthly traffic levels, email sending volumes, etc. This will help determine if a shared IP has enough capacity or if you need a dedicated resource.
Consider Future Growth
While current usage might be low, project future growth. Locking in dedicated IPs now allows headroom to scale up sites, traffic, and email down the road.
Mind Security Obligations
If you handle highly sensitive data or have regulatory security requirements, isolate things as much as possible with dedicated IPs to limit risks.
Weigh the Importance of Perception
Some larger brands prefer the perceived professionalism and security of dedicated IPs. But don’t overspend just for perception – understand the technical differences.
Determine Management Preferences
Managing dedicated IPs requires more hands-on administration. Are you equipped for this or would you prefer a provider to handle management of shared IPs?
Check Provider Offerings
Not all hosts offer dedicated IPs.factor IP options into your provider decision if dedicated IPs are a firm requirement.
Discuss Options with Providers
Have candid discussions with prospective providers about your goals and concerns. Let them help assess dedicated vs shared IPs for your scenario.
Start Lean, Then Scale
When in doubt, start with cost-effective shared hosting/IPs. Monitor your growth and upgrade to dedicated resources later as needed.
Combine for Flexibility
One option is to use shared resources for most sites, but splurge on dedicated IPs for your highest traffic, most security-critical domains.
Evaluating your current and future needs will make the best IP approach clear. Mix and match shared and dedicated IPs where appropriate to find your ideal balance of cost, performance, and control.
With the information in this guide, you now have a complete picture of the dedicated vs shared IP landscape. The great news is that today’s modern networks mean both options are extremely viable for hosting robust, high-performing websites and email platforms.
Key Takeaways: Choosing Between Dedicated and Shared IP Addresses
The choice between using a dedicated IP address or shared IP address for your websites and email sending depends on your specific needs.
Dedicated IP addresses provide:
- Complete ownership and control over reputation and security
- Ability to send high email volumes with consistent deliverability
- Isolation for hosting sensitive data and mission-critical sites
- Flexibility for advanced custom networking and configurations
- Perception of professionalism and enterprise-level infrastructure
Shared IP addresses offer:
- Extremely affordable website hosting
- Easy and instant setup, no IP warming required
- Load balancing and burden sharing with other users
- Ability to start small and upgrade later as needed
- Leveraging of reputation of established sites on shared IPs
For most small sites and modest email volumes, a shared IP will be the best fit and most cost-effective option. As your network usage grows and becomes more complex, transitioning to dedicated IPs may be warranted.
Combining shared and dedicated IPs can provide the perfect balance of value and customization too. Evaluate all your options and work with knowledgeable providers to map out the ideal IP strategy.
Frequently Asked Questions
Q: Is a dedicated IP better for SEO?
A: No, using a dedicated IP will provide no SEO boost over a shared IP. Google has confirmed IP addresses are not a ranking factor. Focus on quality content and good technical SEO practices, not IP configuration.
Q: Can I use a free VPN instead of paying for dedicated IPs?
A: Free VPNs often have bandwidth limits, shared IPs, retain logs, and could hurt your email deliverability if IPs get blacklisted. Paid VPNs are more reliable if you require anonymization.
Q: Are dedicated IPs faster than shared?
A: Not inherently. With quality hosting, both dedicated and shared IPs can deliver excellent site performance. Dedicated IPs simply remove the variability of other sites on shared IPs affecting yours.
Q: Can I switch between shared and dedicated IPs?
A: Absolutely. Many hosts make it easy to upgrade from shared to dedicated. Evaluate your traffic and email volume regularly to determine the best IP setup over time.
Q: Will switching web hosting companies impact my SEO?
A: As long as your domain name remains the same, changing web hosts and IP addresses will not hurt SEO or rankings. New IPs require a brief DNS propagation but then traffic resumes as normal.
Q: How many emails per month need a dedicated IP?
A: There is no firm threshold, but most experts recommend dedicated IPs once your monthly volume exceeds 100,000-200,000 emails. Maintain deliverability at lower volumes with reputable shared IPs.
Q: Can I transfer my dedicated IP to a new provider?
A: Unfortunately, no. Your dedicated IP is tied to your account configuration on your current host. You’ll need to obtain a new dedicated IP when switching providers.
Q: Is a dedicated IP needed for SSL certificates?
A: Not anymore. Nearly all modern sites can use SSL certificates perfectly fine on shared hosting and IPs thanks to SNI (Server Name Indication) technology.
