Each active domain is registered on the name of a particular person and throughout the registration process a lot of details are presented - the owner’s names, address, email, contact number, and so on. This information plus the registrar company name and the registration/expiration dates is referred to as WHOIS of the domain address and in accordance with the policies of Internet Corporation for Assigned Names and Numbers (ICANN) it must be current and accurate. If a domain name has wrong WHOIS details, it might be reported and if the details aren't fixed, the domain address can be erased or the registrar company may take over its ownership. By default, the WHOIS details are public and can be seen on numerous lookup sites, or for a small number of country-code extensions - on the sites of the respective Registry companies. All companies which provide registration services are required to provide an effective way for their clients to access and modify the WHOIS information of any domain address they own as much as the particular TLD allows it.
