Every active domain name is registered on the name of a person and during the registration process numerous details are submitted - the owner’s names, address, email, mobile phone number, and many others. This info combined with the registrar company name and the registration/expiration dates is addressed as WHOIS of the domain and in accordance with the policies of Internet Corporation for Assigned Names and Numbers (ICANN) it should be current and correct. If a domain address has wrong WHOIS details, it may be reported and if the details aren't fixed, the domain may be erased or the registrar company may take over its ownership. By default, the WHOIS information is public and could be seen on a lot of lookup Internet sites, or for a limited number of country-code extensions - on the sites of the respective Registry businesses. All companies which provide registration services are required to provide an effective way for their customers to access and change the WHOIS info of any domain address they own as much as the specific TLD allows it.
