This site offers a WHOIS lookup service that allows you to perform a WHOIS lookup on a domain name to see who owns it or to see if it is available for registration. This service queries the appropriate WHOIS server for the domain name and displays the response which is a public record that anyone can see. In some cases, the owner of a domain name (the "registrant") may choose not to display its address and contact information.

Supported TLDs: .COM .EUROVISION .VISION .RADIO .MUSIC .NAME and .CC
