About Class C IP Checker

Enter a list of domains to see their IP addresses and Class C range. Sites on the same range are often on the same host or network. SEOs use this to check whether a network of sites looks related, and site owners use it to see who shares their server neighbourhood.

How to use the Class C IP Checker

  1. 1Enter the domains or URLs you want to check, one per line.
  2. 2Click the button to check them all at once.
  3. 3Compare the results in the table and act on any that need attention.

Frequently asked questions

What is a Class C IP range?

It is the first three parts of an IPv4 address, for example 203.0.113 in 203.0.113.25. Sites that share it are usually hosted on the same network.

Does sharing a Class C range hurt SEO?

Not on its own. Millions of normal sites share hosting ranges. It only matters if you run a network of sites linking to each other, which can look artificial.
