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