WHOIS is a protocol which makes it an easy task to see the details a particular domain has been registered with either through a command line or with the help of special web-based lookup websites. This information includes the names, address and email address of the owner, administrator, tech and billing persons plus the registrar organization the domain address has been purchased through, the creation and expiration dates. Except for several country-code TLDs that have certain limitations, the WHOIS info of any Internet domain 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 ought to be current and correct all of the time. Inability to conform with these policies could lead to losing the ownership of a domain address and in some cases a domain could even be deleted from the Domain Name System and released for free registration.
