Each and every active domain is registered on the name of a person and through the registration procedure a lot of details are introduced - the owner’s names, address, e-mail, mobile phone number, and so on. This information in addition to the registrar company name and the registration/expiration dates is called WHOIS of the Internet domain and in accordance with the policies of Internet Corporation for Assigned Names and Numbers (ICANN) it ought to be current and accurate. If a domain address has wrong WHOIS details, it may be reported and if the details are not corrected, the domain address may be deleted or the registrar company may take over its ownership. By default, the WHOIS info is public and could be seen on many lookup websites, or for a small number of country-code extensions - on the sites of the respective Registry businesses. All companies which offer registration services are obligated to provide a simple way for their clients to access and modify the WHOIS info of any domain name they own as much as the particular TLD allows it.
