Each active domain name is registered on the name of a person and during the registration process a lot of details are introduced - the owner’s names, address, email, mobile phone number, and many others. These details combined with the registrar company name and the registration/expiration dates is called WHOIS of the domain and in agreement with the policies of Internet Corporation for Assigned Names and Numbers (ICANN) it needs to be current and accurate. If a domain address has invalid WHOIS details, it could be reported and if the details aren't fixed, the domain address can be deleted or the registrar company could take over its ownership. By default, the WHOIS details are public and can be seen on various lookup sites, or for a smaller number of country-code extensions - on the Internet sites of the respective Registry companies. All businesses that offer registration services are obligated to provide a simple way for their customers to access and edit the WHOIS information of any Internet domain they own as much as the particular TLD allows it.
