Every active domain is registered on the name of a particular person and through the registration process a lot of details are introduced - the owner’s names, address, e-mail, mobile phone number, and so on. This info along with 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 should be current and legitimate. If a domain has wrong WHOIS details, it can be reported and if the details are not corrected, the domain name can be deleted or the registrar company could take over its ownership. By default, the WHOIS information is public and can be seen on various lookup Internet sites, or for a limited number of country-code extensions - on the sites of the respective Registry organizations. All businesses that offer registration services are required to provide a simple way for their customers to access and modify the WHOIS information of any domain name they own as much as the specific TLD allows it.
