WHOIS is a protocol that makes it possible to view the details a given domain has been registered with either through a command line or through the use of special web-based lookup websites. This info includes the names, address and e-mail address of the owner, admin, tech and billing persons as well as the registrar business the domain address has been acquired through, the creation and expiration dates. Apart from a number of country-code TLDs that have certain limitations, the WHOIS info of any domain address can be edited freely whenever you want, which is quite vital provided that based on the policies of the top-level Internet Corporation, ICANN, all details ought to be current and legitimate always. Failure to comply with these policies may result in losing the ownership of a domain address and in many cases a domain address could even be erased from the Domain Name System and released for free registration.
