WHOIS is a protocol which makes it simple to see the details a given domain name has been registered with through a command line or using special web-based lookup sites. This information includes the names, address and e-mail address of the owner, administrator, technical and billing persons as well as the registrar business the domain name has been acquired through, the creation and expiration dates. Apart from a few country-code TLDs that have certain limitations, the WHOIS info of any domain can be edited freely whenever you want, which is quite vital given that based on the policies of the top-level Internet Corporation, ICANN, all details have to be current and legitimate at all times. Inability to conform with these policies could lead to losing the ownership of an Internet domain and in many cases a domain could even be deleted from the Domain Name System and released for free registration.
