Each active domain name is registered on the name of a particular person and during the registration process a lot of details are submitted - the owner’s names, address, email, telephone number, and so on. These details combined with the registrar company name and the registration/expiration dates is known as WHOIS of the domain and in compliance with the policies of Internet Corporation for Assigned Names and Numbers (ICANN) it has to be current and correct. If a domain has invalid WHOIS details, it could be reported and if the details are not corrected, the domain may be erased or the registrar company could take over its ownership. By default, the WHOIS info is public and may be seen on a lot of lookup Internet sites, or for a smaller number of country-code extensions - on the sites of the respective Registry businesses. All companies that provide registration services are obliged to provide an easy way for their customers to access and edit the WHOIS details of any domain address they own as much as the particular TLD allows it.
