A Class C IP Checker Tool helps you determine whether multiple domains are hosted on the same Class C IP address. Class C IP addresses are part of the IPv4 system and are often used to identify networks. In SEO, checking Class C IPs is important because backlinks from domains hosted on the same Class C IP may carry less weight than those from diverse IPs.
