Every active domain is registered on the name of an individual and during the registration process a number of details are submitted - the owner’s names, address, e-mail, telephone number, and so forth. This info as well as the registrar company name and the registration/expiration dates is referred to as WHOIS of the domain and in agreement with the policies of Internet Corporation for Assigned Names and Numbers (ICANN) it should be current and correct. If an Internet domain has invalid WHOIS details, it could be reported and if the details are not corrected, the Internet domain could be deleted or the registrar company could take over its ownership. By default, the WHOIS information is public and can be seen on a lot of lookup sites, or for a small number of country-code extensions - on the Internet sites of the respective Registry businesses. All companies which offer registration services are obligated to provide a simple way for their clients to access and modify the WHOIS information of any Internet domain they own as much as the specific TLD allows it.
