Frequently Asked Questions

Does sharing an IP mean the sites are related?
Not necessarily — many unrelated sites share hosting infrastructure on shared or cloud hosting, so this is a data point, not proof of a connection on its own.

Is this tool free?
Yes, using the reverse IP checker is completely free.

Frequently Asked Questions

Why would I check for domains on the same IP?

It reveals whether a site is on shared hosting, helps investigate suspicious neighboring sites that could affect IP reputation, and supports competitive research into a hosting provider's other clients.

Why might no other domains show up?

The site may be on a dedicated IP with no other domains, behind a CDN or reverse proxy that masks the origin server, or the lookup source may not have indexed every domain sharing that IP.

Does sharing an IP with a bad site hurt my SEO?

Modern search engines are generally good at attributing ranking signals per-domain rather than per-IP, so shared hosting alone is rarely a ranking problem — though a dedicated IP can still matter for other technical or compliance reasons.

Is this tool free to use?

Yes, running a reverse IP lookup is completely free, with no signup or usage limit.
