Each active domain is registered on the name of an individual and during the registration process many details are presented - the owner’s names, address, email, contact number, and so on. This information along with the registrar company name and the registration/expiration dates is known as WHOIS of the Internet domain and in compliance with the policies of Internet Corporation for Assigned Names and Numbers (ICANN) it ought to be current and correct. If a domain address has invalid WHOIS details, it could be reported and if the details are not corrected, the domain name can be deleted or the registrar company may take over its ownership. By default, the WHOIS info is public and can be seen on various lookup sites, or for a limited number of country-code extensions - on the Internet sites of the respective Registry companies. All companies which provide registration services are obliged to provide an easy way for their customers to access and modify the WHOIS information of any Internet domain they own as much as the particular TLD allows it.
