Effects of IP Class and Server on SEO

Search Engine Optimization (SEO) is one of the fields whose importance is increasing every day with digitalization and the growth of e-commerce. Website owners who conduct SEO work may sometimes overlook important metrics. Domain Class IP and server-side scans are also among the important SEO metrics.

What is Class IP?

Class IPs are the names given to the classes where websites are located between certain IP addresses. There are 5 different class IP categories here.

• Class A IP


• Class B IP


• Class C IP


• Class D IP


• Class E IP

In these classes, Class A IP represents the range between addresses 1.0.0.1 and 126.255.255.254, Class B IP between 128.1.0.1 and 191.255.255.254, Class C IP between 192.0.1.1 and 223.255.254.254, Class D IP between 224.0.0.0 and 239.255.255.255, and Class E IP between 240.0.0.0 and 254.255.255.254.

The Impact of Class IPs on SEO

Class IPs generally represent the IP addresses where websites are located. Since Class D and E IPs are usually used for developer-related purposes, they are not found on the world wide web. Among Class A, B, and C IP addresses, the most valuable are Class A IPs. This is because Class A IP addresses are harder to obtain and represent the group of IPs where many valuable websites on the internet are hosted. For this reason, access to these IPs is quite difficult and costly.

Therefore, websites with Class A IPs are highly valued by search engines. Since their costs are very high, websites with Class A IP addresses are known to have index and authority priority by search engines. About 75–80% of the websites hosted on the web consist of Class B and Class C IPs. From this, you can understand how valuable Class A IPs are.

Server and SEO Relationship

One of the common mistakes after publishing a website is starting SEO efforts without checking which server the website is hosted on. Hosting companies generally use shared hosting servers for websites, and multiple websites can be hosted on the same server as your website.

This situation may negatively affect the visibility of your website if one of the websites on the same server;

• is penalized by search engines,


• hosts illegal, gambling, violent, etc. content,


• contains duplicate content,


• falls into spam or sandbox status

In such harmful cases, the server IP address may be restricted by search engines, negatively impacting your website’s visibility as well. To prevent this, a server scan must be performed.

After visiting the relevant address, simply paste your website into the box above and click query.

Once the scan is complete, as you can see in the image above, other websites hosted on the same server will be listed. These websites should be checked, and if there is any harmful website, it should be reported to the hosting company immediately.

How to Exit a Server Hosting Harmful Sites?

If you think your website may be harmed by other sites hosted on the same server, you can purchase a static IP address for your website, ensuring it has its own IP address instead of the server IP and can be customized.

Another method is to contact your hosting company, inform them of the situation, and request that your website be moved to a different server. Hosting companies usually handle such cases with understanding and will move your website to a different server without charging you.

Additionally, during your scan, you can view websites sharing the same Class C IP address as yours, and if there are websites you consider harmful, you can again contact your hosting provider and request to be moved to a different Class IP address.
