Each active domain is registered on the name of an individual and through the registration process a number of details are submitted - the owner’s names, address, email, cell phone number, and so on. This info in addition to 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 needs to be current and legitimate. If a domain has invalid WHOIS details, it might be reported and if the details are not fixed, 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 a lot of lookup 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 obliged to provide a simple way for their clients to access and modify the WHOIS details of any domain address they own as much as the specific TLD allows it.
