Every active domain name is registered on the name of a particular person and through the registration procedure numerous details are presented - the owner’s names, address, email, mobile phone number, and so on. These details as well as the registrar company name and the registration/expiration dates is recognized as WHOIS of the domain name and in agreement with the policies of Internet Corporation for Assigned Names and Numbers (ICANN) it needs to be current and legitimate. If a domain name has incorrect WHOIS details, it can be reported and if the details are not corrected, the domain address can be deleted or the registrar company could take over its ownership. By default, the WHOIS information is public and could be seen on a lot of lookup websites, or for a limited number of country-code extensions - on the Internet sites of the respective Registry businesses. All companies that provide registration services are obliged to provide an uncomplicated way for their clients to access and change the WHOIS details of any domain address they own as much as the particular TLD allows it.
