Each active domain is registered on the name of an individual and throughout the registration process a lot of details are introduced - the owner’s names, address, email, phone number, and so on. This info along with the registrar company name and the registration/expiration dates is called WHOIS of the domain and in compliance with the policies of Internet Corporation for Assigned Names and Numbers (ICANN) it must be current and accurate. If a domain address has invalid WHOIS details, it may be reported and if the details are not fixed, the domain name may be deleted or the registrar company may take over its ownership. By default, the WHOIS information is public and may be seen on a lot of lookup sites, or for a smaller number of country-code extensions - on the Internet sites of the respective Registry organizations. All companies that offer registration services are obligated to provide an effective way for their customers to access and modify the WHOIS information of any domain they own as much as the specific TLD allows it.
