WHOIS is a protocol which makes it simple to see the info a specific domain name has been registered with either through a command line or through the use of special web-based lookup sites. This info includes the names, address and e-mail address of the owner, admin, tech and billing persons in addition to the registrar business the domain has been obtained through, the creation and expiration dates. With the exception of several country-code TLDs that have specific limitations, the WHOIS information of any Internet domain can be edited freely whenever you want, which is quite important considering that in line with the policies of the top-level Internet Corporation, ICANN, all details must be current and legitimate always. Failing to comply with these policies could lead to losing the ownership of an Internet domain and in some cases a domain might even be deleted from the Domain Name System and released for free registration.
