Every active domain name is registered on the name of a particular person and throughout the registration process many details are submitted - the owner’s names, address, e-mail, phone number, and many others. These details as well as the registrar company name and the registration/expiration dates is known as WHOIS of the domain name and in accordance with the policies of Internet Corporation for Assigned Names and Numbers (ICANN) it should be current and accurate. If a domain has invalid WHOIS details, it could be reported and if the details aren't fixed, the Internet domain may be deleted or the registrar company could take over its ownership. By default, the WHOIS information is public and could be seen on numerous lookup Internet sites, or for a small number of country-code extensions - on the Internet sites of the respective Registry organizations. All companies that provide registration services are required to provide a simple way for their clients to access and modify the WHOIS information of any domain name they own as much as the specific TLD allows it.
