Each and every active domain name is registered on the name of a particular person and during the registration procedure many 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 addressed 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 name has wrong WHOIS details, it may be reported and if the details are not fixed, the Internet domain may be deleted or the registrar company could take over its ownership. By default, the WHOIS details are 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 provide registration services are obligated to provide an uncomplicated way for their customers to access and modify the WHOIS details of any domain address they own as much as the particular TLD allows it.
