WHOIS is a protocol which makes it easy to see the info a specific domain name has been registered with either through a command line or using special web-based lookup sites. This info includes the names, address and e-mail address of the owner, admin, technical and billing persons as well as the registrar organization the Internet domain has been obtained through, the creation and expiration dates. Apart from several country-code TLDs that have certain limitations, the WHOIS details of any domain name can be edited freely at any time, which is quite vital provided that in line with the policies of the top-level Internet Corporation, ICANN, all details ought to be current and valid all of the time. Failure to conform with these policies may lead to losing the ownership of a domain and in many cases a domain address could even be erased from the Domain Name System and released for free registration.
