WHOIS is a protocol that makes it easy to see the details a given domain name has been registered with either through a command line or with the help of special web-based lookup websites. This info includes the names, address and e-mail address of the owner, admin, technical and billing persons plus the registrar business the domain name has been acquired through, the creation and expiration dates. Aside from a few country-code TLDs that have specific limitations, the WHOIS details of any domain can be modified freely at any time, which is quite vital provided that based on the policies of the top-level Internet Corporation, ICANN, all details must be current and valid always. Failing to comply with these policies could lead to losing the ownership of an Internet domain and in some cases a domain may even be deleted from the Domain Name System and released for free registration.
