Each and every active domain is registered on the name of a person and throughout the registration process a number of details are introduced - the owner’s names, address, email, phone number, etc. These details in addition to 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 has invalid WHOIS details, it can be reported and if the details aren't fixed, the domain address could be deleted or the registrar company could take over its ownership. By default, the WHOIS details are public and can be seen on many lookup sites, or for a small number of country-code extensions - on the sites of the respective Registry organizations. All businesses that offer registration services are obligated to provide an uncomplicated way for their customers to access and edit the WHOIS details of any Internet domain they own as much as the particular TLD allows it.
