WHOIS is a protocol which makes it an easy task to view the info a specific domain has been registered with through a command line or by using special web-based lookup sites. This information includes the names, address and e-mail address of the owner, admin, technical and billing persons along with the registrar company the domain has been obtained through, the creation and expiration dates. Apart from a number of country-code TLDs that have certain limitations, the WHOIS info of any domain address can be changed freely at any time, which is quite important 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 may lead to losing the ownership of a domain address and in many cases a domain name may even be erased from the Domain Name System and released for free registration.
