Are Class C Addresses Preferred by SEOs?

Most of the hosting service providers are assigned class C IP addresses. They in turn assign unique or dynamic addresses to their customers. Most of the public sector customers prefer to use dynamic addresses. The reason for this is that they are cheaper than static addresses. For example, if you have two or more websites, you can have them hosted on a single hosting service. Which means you are not paying for hosting two domains, instead you are paying for one. However both your websites will be available when a visitor wants to visit them. The dynamic addressing is handled by the web hosting service providers systems.

Since the bulk of websites exist in the C class IP addresses, the search engines can process the backlinks to a site much faster and can check the quality and status of the link. The fight for better ranking on search engines takes place among websites that have C Class IP addresses.

At times hosting services can assign the same IP address to two entirely different domains. In this case should you run the cache command to check the last status of your website that Google has stored you might be shocked to see another website’s image cached on your domain name.
