Every active domain is registered on the name of an individual and during the registration process a lot of details are submitted - the owner’s names, address, e-mail, cell phone number, and many others. These details plus 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 legitimate. If an Internet domain has wrong WHOIS details, it could be reported and if the details are not corrected, the domain may be deleted or the registrar company may take over its ownership. By default, the WHOIS information is public and can be seen on many lookup Internet sites, or for a smaller number of country-code extensions - on the websites of the respective Registry organizations. All companies that offer registration services are obliged to provide an effective way for their customers to access and modify the WHOIS information of any domain name they own as much as the particular TLD allows it.
