Each active domain is registered on the name of a particular person and through the registration process a number of details are submitted - the owner’s names, address, e-mail, telephone number, and many others. This info in addition to the registrar company name and the registration/expiration dates is referred to as WHOIS of the domain and in accordance with the policies of Internet Corporation for Assigned Names and Numbers (ICANN) it should be current and legitimate. If a domain name has invalid WHOIS details, it could be reported and if the details aren't corrected, the domain address may be deleted or the registrar company could take over its ownership. By default, the WHOIS details are public and could be seen on numerous lookup Internet sites, or for a smaller number of country-code extensions - on the Internet sites of the respective Registry companies. All companies which offer registration services are obliged to provide an easy way for their clients to access and change the WHOIS information of any Internet domain they own as much as the particular TLD allows it.
