WHOIS is a protocol which 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 info includes the names, address and email address of the owner, admin, tech and billing persons plus the registrar business the Internet domain has been obtained through, the creation and expiration dates. Except for some country-code TLDs that have specific limitations, the WHOIS details of any domain can be edited freely anytime, which is quite vital provided that based on the policies of the top-level Internet Corporation, ICANN, all details have to be current and legitimate all of the time. Failure to comply with these policies may lead to losing the ownership of an Internet domain and in many cases a domain name could even be removed from the Domain Name System and released for free registration.
