Every active domain name is registered on the name of a person and through the registration procedure numerous details are introduced - the owner’s names, address, e-mail, telephone number, and so on. These details combined with the registrar company name and the registration/expiration dates is known as WHOIS of the domain address and in compliance with the policies of Internet Corporation for Assigned Names and Numbers (ICANN) it has to be current and correct. If a domain has invalid WHOIS details, it might be reported and if the details are not corrected, the Internet domain may be deleted or the registrar company could take over its ownership. By default, the WHOIS information is public and can be seen on many lookup websites, or for a smaller number of country-code extensions - on the Internet sites of the respective Registry companies. All businesses that offer registration services are obliged to provide a simple way for their clients to access and modify the WHOIS info of any Internet domain they own as much as the specific TLD allows it.
