Each active domain is registered on the name of a particular person and during the registration process a number of details are submitted - the owner’s names, address, e-mail, phone number, and so on. This info plus the registrar company name and the registration/expiration dates is called WHOIS of the domain and in accordance with the policies of Internet Corporation for Assigned Names and Numbers (ICANN) it must be current and legitimate. If a domain name has invalid WHOIS details, it might be reported and if the details are not corrected, the domain name could be erased or the registrar company may take over its ownership. By default, the WHOIS details are public and may be seen on various lookup sites, or for a limited number of country-code extensions - on the sites of the respective Registry companies. All businesses that offer registration services are required to provide an uncomplicated way for their customers to access and edit the WHOIS details of any Internet domain they own as much as the specific TLD allows it.
