WHOIS is a protocol which makes it possible to see the details a specific domain has been registered with either through a command line or by 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 domain address has been acquired through, the creation and expiration dates. Aside from a few country-code TLDs that have certain limitations, the WHOIS info of any domain address can be edited freely whenever you want, which is quite important given that based on the policies of the top-level Internet Corporation, ICANN, all details have to be current and legitimate always. Failure to conform with these policies may lead to losing the ownership of a domain name and in many cases a domain name could even be removed from the Domain Name System and released for free registration.
