WHOIS is a protocol that makes it simple to see the info a particular domain name has been registered with either through a command line or by using special web-based lookup websites. This information includes the names, address and e-mail address of the owner, admin, tech and billing persons along with the registrar company the Internet domain has been acquired through, the creation and expiration dates. Apart from some country-code TLDs that have specific limitations, the WHOIS information of any domain name can be edited freely anytime, which is quite necessary provided that in line with the policies of the top-level Internet Corporation, ICANN, all details have to be current and correct all of the time. Failing to comply with these policies may result in losing the ownership of an Internet domain and in many cases a domain name could even be removed from the Domain Name System and released for free registration.
