WHOIS is a protocol that makes it easy to see the information a particular domain name has been registered with through a command line or with the help of special web-based lookup websites. This info includes the names, address and e-mail address of the owner, administrator, tech and billing persons in addition to the registrar business the Internet domain has been obtained through, the creation and expiration dates. Apart from several country-code TLDs that have specific limitations, the WHOIS information of any domain address can be edited freely anytime, which is quite vital since in accordance with the policies of the top-level Internet Corporation, ICANN, all details must be current and legitimate always. Failure to conform with these policies may lead to losing the ownership of a domain name and in some cases a domain name may even be deleted from the Domain Name System and released for free registration.
