Internet - Who Owns That Domain Name?
When visiting a website, you may wonder who it belongs to, especially if there's little contact information available at the site. To find out who owns a domain name, investigate using a whois tool. A whois tool searches domain registry databases for information about a domain name's availability and ownership information.
Most domain name registrars provide a whois tool on their site's front page, or you can do a keyword search on "whois" in your favorite search engine.
