WHOIS is a protocol which makes it an easy task to see the info a specific domain name has been registered with either through a command line or by using special web-based lookup websites. This info includes the names, address and e-mail address of the owner, administrator, tech and billing persons in addition to the registrar business the domain has been purchased through, the creation and expiration dates. With the exception of a few country-code TLDs that have certain limitations, the WHOIS info of any domain can be edited freely anytime, which is quite vital provided that in accordance with the policies of the top-level Internet Corporation, ICANN, all details have to be current and valid always. Failing to conform with these policies may lead to losing the ownership of a domain and in some cases a domain name could even be deleted from the Domain Name System and released for free registration.
