Each and every active domain name is registered on the name of a person and during the registration process a lot of details are introduced - the owner’s names, address, email, mobile phone number, etc. This info plus the registrar company name and the registration/expiration dates is called WHOIS of the domain address and in agreement with the policies of Internet Corporation for Assigned Names and Numbers (ICANN) it ought to be current and correct. If a domain name has invalid WHOIS details, it could be reported and if the details are not fixed, the Internet domain may be erased or the registrar company could take over its ownership. By default, the WHOIS details are public and can be seen on numerous lookup Internet sites, or for a small number of country-code extensions - on the sites of the respective Registry businesses. All companies which offer registration services are required to provide a simple way for their clients to access and change the WHOIS details of any domain address they own as much as the specific TLD allows it.
