Every active domain is registered on the name of an individual and during the registration process a lot of details are introduced - the owner’s names, address, email, telephone number, and so on. These details as well as the registrar company name and the registration/expiration dates is referred to as WHOIS of the domain and in compliance with the policies of Internet Corporation for Assigned Names and Numbers (ICANN) it must be current and correct. If a domain address has invalid WHOIS details, it can be reported and if the details aren't corrected, the domain name can be deleted or the registrar company may 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 Internet sites of the respective Registry organizations. All companies which offer registration services are obligated to provide an easy way for their customers to access and change the WHOIS information of any domain they own as much as the specific TLD allows it.
