WHOIS is a protocol that makes it an easy task to see the information a particular domain has been registered with either through a command line or through the use of special web-based lookup sites. This information includes the names, address and email address of the owner, admin, tech and billing persons as well as the registrar business the domain has been acquired through, the creation and expiration dates. Except for a few country-code TLDs that have certain limitations, the WHOIS information of any domain name can be edited freely whenever you want, which is quite necessary since based on the policies of the top-level Internet Corporation, ICANN, all details ought to be current and correct all of the time. Failure to comply with these policies could lead to losing the ownership of an Internet domain and in many cases a domain might even be deleted from the Domain Name System and released for free registration.
