Each active domain is registered on the name of a person and throughout the registration process a lot of details are introduced - the owner’s names, address, email, mobile phone number, and many others. This info along with the registrar company name and the registration/expiration dates is recognized as WHOIS of the domain address and in compliance with the policies of Internet Corporation for Assigned Names and Numbers (ICANN) it should be current and correct. If a domain name has incorrect WHOIS details, it may be reported and if the details aren't fixed, the Internet domain could be erased or the registrar company could take over its ownership. By default, the WHOIS info is public and could be seen on numerous lookup Internet sites, or for a small number of country-code extensions - on the websites of the respective Registry organizations. All companies that provide registration services are required to provide a simple way for their customers to access and modify the WHOIS information of any domain name they own as much as the specific TLD allows it.
