Each and every active domain name is registered on the name of a person and throughout the registration procedure a lot of details are presented - the owner’s names, address, email, mobile phone number, etc. This info as well as the registrar company name and the registration/expiration dates is referred to as WHOIS of the Internet domain and in accordance with the policies of Internet Corporation for Assigned Names and Numbers (ICANN) it ought to be current and legitimate. If an Internet domain has invalid WHOIS details, it can be reported and if the details aren't fixed, the Internet domain may be erased or the registrar company could take over its ownership. By default, the WHOIS details are public and could be seen on various lookup sites, or for a smaller number of country-code extensions - on the Internet sites of the respective Registry companies. All businesses that offer registration services are required to provide a simple way for their clients to access and modify the WHOIS details of any domain name they own as much as the particular TLD allows it.
