WHOIS is a protocol that makes it possible to view the details a given domain name has been registered with 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, admin, tech and billing persons in addition to the registrar organization the domain address has been obtained through, the creation and expiration dates. Aside from a number of country-code TLDs that have certain limitations, the WHOIS info of any Internet domain can be edited freely at any time, which is quite important considering that in accordance with the policies of the top-level Internet Corporation, ICANN, all details must be current and valid all of the time. Inability to conform with these policies may result in losing the ownership of a domain name and in many cases a domain address could even be deleted from the Domain Name System and released for free registration.
