Each active domain name is registered on the name of an individual and through the registration procedure many details are submitted - the owner’s names, address, email, cell phone number, and many others. This information plus 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 must be current and legitimate. If an Internet domain has incorrect WHOIS details, it might be reported and if the details are not fixed, the domain may be deleted or the registrar company may take over its ownership. By default, the WHOIS information is public and could be seen on many lookup sites, or for a small number of country-code extensions - on the Internet sites of the respective Registry businesses. All companies that provide registration services are required to provide an effective way for their clients to access and change the WHOIS information of any Internet domain they own as much as the specific TLD allows it.
