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.
