Whois query - find out who owns a Domain or IP address

This ("who is") lookup tool can be used to find out who owns a domain, or who is behind an IP address.

Whois protocol

WHOIS ("Who is") is a protocol on the internet that can be used to find out the registered user of a domain or IP address.

On a Unix/Linux based computer, the 'whois' command can be used to query the database for a specific domain name or IP address. You can do the same online with this tool. If you enter a domain name like "manytools.org", the whois tool will display the registry information for this domain, including the IP address of the server it's hosted on.

Migrated to HTTPS

Happy to inform that Manytools is now fully Chrome-62-ready, thanks Google! A secure connection had been due for a very long time. Today we finally got around to upgrading the site to run on HTTPS. – (Starting October 2017, Chrome (version 62) will show a “NOT SECURE” warning when users enter text in a form on an HTTP page, and for all HTTP pages in Incognito mode.)
