WHOIS is a protocol which makes it an easy task to view the info a specific domain name has been registered with through a command line or using special web-based lookup sites. This information includes the names, address and e-mail address of the owner, admin, tech and billing persons along with the registrar company the domain has been purchased through, the creation and expiration dates. Apart from some country-code TLDs that have certain limitations, the WHOIS information of any domain address can be edited freely anytime, which is quite important considering that according to the policies of the top-level Internet Corporation, ICANN, all details have to be current and legitimate at all times. Inability to conform with these policies may result in losing the ownership of a domain name and in many cases a domain might even be erased from the Domain Name System and released for free registration.
