Every active domain name is registered on the name of a particular person and throughout the registration process many details are introduced - the owner’s names, address, email, cell phone number, and so forth. This information as well as the registrar company name and the registration/expiration dates is referred to as WHOIS of the Internet domain and in agreement with the policies of Internet Corporation for Assigned Names and Numbers (ICANN) it ought to be current and correct. If a domain address has wrong WHOIS details, it might be reported and if the details are not corrected, the domain name can be deleted or the registrar company may take over its ownership. By default, the WHOIS info 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 companies. All companies which provide registration services are obligated to provide an effective way for their clients to access and modify the WHOIS information of any domain they own as much as the particular TLD allows it.
