Each active domain name is registered on the name of an individual and during the registration process many details are introduced - the owner’s names, address, email, phone number, etc. This info plus the registrar company name and the registration/expiration dates is called WHOIS of the domain address and in compliance with the policies of Internet Corporation for Assigned Names and Numbers (ICANN) it ought to be current and legitimate. If a domain address has invalid WHOIS details, it might be reported and if the details aren't corrected, the domain could be erased 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 limited number of country-code extensions - on the Internet sites of the respective Registry businesses. All companies that offer registration services are obligated to provide an easy way for their customers to access and modify the WHOIS info of any domain address they own as much as the specific TLD allows it.
