Each and every active domain is registered on the name of a person and during the registration procedure many details are submitted - the owner’s names, address, email, phone number, and many others. These details as well as the registrar company name and the registration/expiration dates is addressed as WHOIS of the domain address and in accordance with the policies of Internet Corporation for Assigned Names and Numbers (ICANN) it needs to be current and legitimate. If an Internet domain has invalid WHOIS details, it may be reported and if the details aren't fixed, the domain address could be erased or the registrar company may take over its ownership. By default, the WHOIS information is public and may be seen on many lookup websites, or for a limited number of country-code extensions - on the websites of the respective Registry organizations. All companies which provide registration services are obliged to provide a simple way for their clients to access and change the WHOIS information of any domain they own as much as the particular TLD allows it.
