Each active domain name is registered on the name of a particular person and throughout the registration procedure a lot of details are submitted - the owner’s names, address, email, contact number, and so forth. This info along with the registrar company name and the registration/expiration dates is referred to as WHOIS of the domain and in compliance with the policies of Internet Corporation for Assigned Names and Numbers (ICANN) it has to be current and accurate. If an Internet domain has invalid WHOIS details, it might be reported and if the details aren't fixed, the domain could be erased or the registrar company could take over its ownership. By default, the WHOIS details are public and could be seen on many lookup websites, or for a small number of country-code extensions - on the Internet sites of the respective Registry organizations. All companies that offer registration services are obliged to provide a simple way for their clients to access and modify the WHOIS information of any domain address they own as much as the specific TLD allows it.
