Each active domain name is registered on the name of a particular person and during the registration procedure a number of details are submitted - the owner’s names, address, e-mail, mobile phone number, and so forth. This information as well as 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 correct. If a domain has invalid WHOIS details, it may be reported and if the details are not corrected, the domain name could be deleted or the registrar company could take over its ownership. By default, the WHOIS info is public and could be seen on a lot of lookup Internet sites, or for a small number of country-code extensions - on the Internet sites of the respective Registry companies. All companies which offer registration services are obligated to provide an easy way for their clients to access and edit the WHOIS info of any domain they own as much as the specific TLD allows it.
