Understanding Dedicated IP Addresses and Their Benefits 




In the complex web of the internet, IP (Internet Protocol) addresses serve as digital postal codes, ensuring data reaches its intended destination. Shared and dedicated IPs each come with distinct advantages that can significantly influence the performance of your web hosting accounts. While shared IPs serve their purpose, it's the dedicated IP that can dramatically elevate your web service. 


In this blog, we will explore the realm of dedicated IP addresses, distinguishing them from shared IPs and uncovering the myriad benefits they offer. 



What is a dedicated IP address? 


A dedicated IP is a unique numeric address assigned exclusively to a single web server or website. Unlike shared IP addresses, it isn't shared with multiple domains. Think of it like having a private mailbox with your unique address, ensuring your mail (data) goes directly to you without mixing with others. 


A dedicated IP address enables improved website performance and stability, better email deliverability, and secure access. It's useful for businesses, especially for hosting websites or sending bulk emails. 


Shared vs. dedicated IP addresses 


Before understanding the difference between shared and dedicated IP addresses, it's essential to start with the foundation: the IP address. 


IP is the set of rules that govern how data is shared across networks. The most commonly used IP format is IPv4, characterized by four sets of 8-bit fields. Here are some examples - and  


Each IP address can be assigned to one unique device within a network. For instance, in a network with three devices, three separate IP addresses are needed - one for each device. Due to the format's limitations, the number of available IP addresses is finite.  


However, sharing a single IP address among multiple domains is possible. For instance, web hosting companies employ this method to offer Shared Hosting services. In Shared Hosting, numerous user accounts use the same physical server. To keep costs low, hosting providers may allocate just one or two IP addresses for all users on that server. In such cases, this is called a shared IP address. 


The primary challenge with IP addresses is the limited number of combinations that providers can assign. Due to this limitation, IP addresses have become a valued resource. When the supply cannot meet the demand, prices naturally rise. As a result, dedicated IP addresses cost more than any shared IP address. 


Here's a table summarizing the key differences between the two: 


Aspect  Shared IP Address  Dedicated IP Address 
Usage  Shared by multiple domains on a single server  Reserved for a single domain or server 
Cost  Cost-effective due to shared usage  Generally more expensive due to exclusivity 
Isolation  Shared with other users, potentially affecting SEO  Better isolation and control 
SSL Certificate   Shared SSL Certificates are common  Allows for a unique SSL Certificate per domain 
Customization and control   Limited control and customization options  Offers greater control and customization 
Potential for blacklisting  Higher risk if another domain on the same IP is blacklisted  Lower risk as the IP is exclusive to your domain 


5 Benefits of a dedicated IP address 


Here are some benefits of utilizing a dedicated IP address: 


1.Enhanced accessibility 


Dedicated IP addresses simplify access to your hosting account from various locations. For instance, if you need to operate an FTP server for rapid file transfers to your host, a dedicated IP accelerates the process, especially for transferring large files. 


2.Greater server control 


While shared IP addresses suffice for web hosting, a dedicated IP offers various potential applications. This is due to the increased server control it provides. Some applications include:  


  • Running a Virtual Private Network (VPN) 
  • Hosting a gaming server 
  • Managing your server remotely 
  • Greater agility when handling files  


3.Increased security 


A dedicated IP address reduces exposure to some security threats. With your exclusive IP, there is no risk of being accidentally targeted by an attack meant for another user. This feature also serves as a defense against certain types of cyberattacks that seek to scan all websites associated with an IP for vulnerabilities. 


4.Improved email deliverability 


When you rely on a shared IP address for managing your emails through your web hosting account, you can face deliverability issues. Email servers are sensitive to IP addresses and may quickly blacklist those they believe as potentially harmful. For instance, if one hosting account on your shared IP begins sending spam, it could lead to the blocking of all your emails. Opting for a dedicated IP can effectively reduce or mitigate this risk. 


5.Essential for SSL Certificates in some cases 


Shared IP addresses utilize Server Name Indication (SNI), which is compatible with most SSL Certificates. However, some SSL Certificates may present compatibility issues, especially with older web browsers. 


A dedicated IP address is required for private SSL Certificates because activation is not possible without it. 


How to get a dedicated IP address? 


You can get a dedicated IP address in a few different ways. One way is to reach out to your internet service provider (ISP) and inquire about their dedicated IP address options. Another way is to acquire a dedicated IP from a web hosting provider.
