WHOIS is a protocol which makes it simple to see the info a specific domain name has been registered with through a command line or with the help of special web-based lookup sites. This info includes the names, address and email address of the owner, administrator, technical and billing persons along with the registrar company the domain address has been purchased through, the creation and expiration dates. With the exception of a few country-code TLDs that have certain limitations, the WHOIS information of any Internet domain can be edited freely whenever you want, which is quite necessary considering that based on the policies of the top-level Internet Corporation, ICANN, all details must be current and correct always. Failure to comply with these policies could lead to losing the ownership of a domain name and in many cases a domain address could even be erased from the Domain Name System and released for free registration.
