WHOIS is a protocol that makes it easy to view the details a specific domain name has been registered with through a command line or through the use of special web-based lookup websites. This information includes the names, address and email address of the owner, admin, tech and billing persons along with the registrar company the domain address has been acquired through, the creation and expiration dates. Except for some country-code TLDs that have certain limitations, the WHOIS details of any domain address can be edited freely whenever you want, which is quite vital considering that in accordance with the policies of the top-level Internet Corporation, ICANN, all details have to be current and correct always. Failing to conform with these policies may result in losing the ownership of a domain name and in many cases a domain name may even be removed from the Domain Name System and released for free registration.
