Learn Who Has Registered a Particular Domain Name
You can learn who has registered a particular domain name by doing a WHOIS search at any domain name registry, including Network Solutions, Register.com, or GoDaddy.com. A WHOIS search is conducted online by entering the domain name, about which you wish to find information into a search box.
The WHOIS search will let you know whether a particular domain name has already been registered. If it has, the WHOIS search will provide you with the following information:
the domain name,
when it was created,
when it was registered,
when it expires,
who administers the domain name,
the address and phone number, and
which company hosts the domain name, the address and phone number.
