Each and every active domain is registered on the name of an individual and through the registration procedure many details are introduced - the owner’s names, address, e-mail, contact number, and many others. These details along with the registrar company name and the registration/expiration dates is called WHOIS of the domain name and in compliance with the policies of Internet Corporation for Assigned Names and Numbers (ICANN) it must be current and legitimate. If a domain has invalid WHOIS details, it could be reported and if the details aren't fixed, the Internet domain could 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 smaller number of country-code extensions - on the sites of the respective Registry businesses. All companies that offer registration services are required to provide an effective way for their customers to access and edit the WHOIS information of any domain name they own as much as the particular TLD allows it.
