Every active domain is registered on the name of a person and through the registration process many details are introduced - the owner’s names, address, email, cell phone number, and so forth. This information in addition to the registrar company name and the registration/expiration dates is addressed as WHOIS of the domain and in compliance with the policies of Internet Corporation for Assigned Names and Numbers (ICANN) it needs to be current and accurate. If an Internet domain has invalid WHOIS details, it could be reported and if the details aren't fixed, the domain name may be erased or the registrar company could take over its ownership. By default, the WHOIS information is public and can be seen on a lot of lookup websites, or for a smaller number of country-code extensions - on the sites of the respective Registry organizations. All companies which offer registration services are obliged to provide an effective way for their customers to access and edit the WHOIS info of any Internet domain they own as much as the particular TLD allows it.
