Every active domain is registered on the name of a person and throughout the registration process a number of details are submitted - the owner’s names, address, email, contact number, and so forth. This info in addition to the registrar company name and the registration/expiration dates is referred to as WHOIS of the domain name and in compliance with the policies of Internet Corporation for Assigned Names and Numbers (ICANN) it ought to be current and legitimate. If an Internet domain has invalid WHOIS details, it can be reported and if the details aren't fixed, the domain may be erased or the registrar company could take over its ownership. By default, the WHOIS details are public and could be seen on many lookup Internet sites, or for a smaller number of country-code extensions - on the sites of the respective Registry companies. All companies which provide registration services are obliged to provide a simple way for their clients to access and modify the WHOIS details of any domain name they own as much as the particular TLD allows it.
