What is a Reverse IP Lookup?

A Reverse IP Lookup queries DNS PTR records and shared hosting databases to find all domain names hosted on a given IP address. It's the opposite of a regular DNS lookup (domain → IP) — it goes from IP → domain(s).

Why would multiple domains share the same IP?

On shared hosting plans, hundreds or even thousands of websites can share the same server IP address. Each domain has its own DNS records pointing to that IP, but they all run on the same physical server.

Is reverse IP lookup the same as PTR record?

A PTR record is one type of reverse DNS entry and typically returns only one hostname (usually the server's own hostname). A full reverse IP lookup also checks shared hosting databases to find all domains pointing to that IP.

Can I use this to check if my IP is used by others?

Yes. If you are on shared hosting, this tool will show you other domains sharing your server IP. This is useful for understanding your hosting environment and potential SEO impact of a bad neighborhood.

Is this reverse IP lookup tool free?

Yes, the Recherche d'IP inverse tool on uptimelock.com is completely free and requires no account.
