Every active domain name is registered on the name of a person and during the registration procedure numerous details are presented - the owner’s names, address, email, telephone number, and so forth. These details as well as the registrar company name and the registration/expiration dates is known as WHOIS of the domain address and in accordance with the policies of Internet Corporation for Assigned Names and Numbers (ICANN) it must be current and correct. If a domain has incorrect WHOIS details, it might be reported and if the details aren't 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 various lookup websites, or for a small number of country-code extensions - on the Internet sites of the respective Registry businesses. All companies which offer registration services are obliged to provide an effective 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.
