WHOIS is a protocol which makes it simple to see the info a particular domain name has been registered with through a command line or through the use of special web-based lookup websites. This info includes the names, address and e-mail address of the owner, administrator, tech and billing persons along with the registrar organization the domain address has been obtained through, the creation and expiration dates. With the exception of a number of country-code TLDs that have specific limitations, the WHOIS details of any Internet domain can be edited freely whenever you want, which is quite important provided that in line with the policies of the top-level Internet Corporation, ICANN, all details must be current and valid at all times. Inability to conform with these policies may lead to losing the ownership of an Internet domain and in many cases a domain address might even be removed from the Domain Name System and released for free registration.
