Enter up to 40 Domains (Each Domain must be on separate line)
The Class C IP Checker is an essential tool for SEO professionals, webmasters, and security analysts who need to verify whether multiple domains are hosted on the same Class C IP range. Search engines like Google may penalize websites that appear to be part of a Private Blog Network (PBN) or manipulative link scheme, often identified by shared hosting IPs. This tool helps you audit backlinks, check competitor hosting setups, and ensure your site maintains IP diversity for better SEO performance.
By entering a list of domains or IPs, you can quickly see which sites share the same first three octets (Class C block) of an IP address. This is crucial for detecting potential PBNs, avoiding footprints in your own SEO campaigns, and ensuring your hosting setup appears natural to search engines. Whether you're conducting competitor research, cleaning up your backlink profile, or verifying hosting security, this free Class C IP Checker provides instant insights to protect your site's rankings and credibility.
