Each active domain is registered on the name of a person and through the registration procedure many details are introduced - the owner’s names, address, e-mail, contact number, and so forth. This information along with the registrar company name and the registration/expiration dates is called WHOIS of the Internet domain and in agreement 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 are not corrected, the Internet domain may be erased or the registrar company may take over its ownership. By default, the WHOIS details are public and can be seen on a lot of lookup sites, or for a limited number of country-code extensions - on the sites of the respective Registry companies. All companies which offer registration services are obliged to provide an easy way for their customers to access and modify the WHOIS info of any Internet domain they own as much as the specific TLD allows it.
