Each and every active domain name is registered on the name of a person and through the registration procedure a number of details are presented - the owner’s names, address, e-mail, contact number, etc. This information as well as the registrar company name and the registration/expiration dates is known as WHOIS of the domain address and in agreement with the policies of Internet Corporation for Assigned Names and Numbers (ICANN) it ought to be current and accurate. If a domain address has invalid WHOIS details, it might be reported and if the details aren't corrected, the domain may be deleted or the registrar company could take over its ownership. By default, the WHOIS information is public and may be seen on various lookup Internet sites, or for a limited number of country-code extensions - on the sites of the respective Registry businesses. All businesses that offer registration services are required to provide an easy way for their customers to access and modify the WHOIS information of any domain they own as much as the particular TLD allows it.
