Each active domain is registered on the name of a particular person and during the registration procedure a number of details are presented - the owner’s names, address, e-mail, cell phone number, and so forth. These details as well as the registrar company name and the registration/expiration dates is known as WHOIS of the Internet domain and in agreement with the policies of Internet Corporation for Assigned Names and Numbers (ICANN) it needs to be current and accurate. If a domain has invalid WHOIS details, it could be reported and if the details are not fixed, the Internet domain can be deleted or the registrar company may take over its ownership. By default, the WHOIS details are public and could be seen on various lookup sites, or for a limited number of country-code extensions - on the websites of the respective Registry organizations. All companies which provide registration services are obliged to provide a simple way for their clients to access and edit the WHOIS information of any domain address they own as much as the specific TLD allows it.
