Each and every active domain name is registered on the name of an individual and during the registration procedure many details are introduced - the owner’s names, address, email, mobile phone number, and so forth. This information plus the registrar company name and the registration/expiration dates is referred to as WHOIS of the domain name and in accordance with the policies of Internet Corporation for Assigned Names and Numbers (ICANN) it needs to be current and accurate. If a domain address has invalid WHOIS details, it might be reported and if the details aren't corrected, the Internet domain can be erased or the registrar company could take over its ownership. By default, the WHOIS information is public and may be seen on numerous lookup websites, or for a smaller number of country-code extensions - on the sites of the respective Registry businesses. All businesses that offer registration services are obliged to provide a simple way for their customers to access and modify the WHOIS information of any domain name they own as much as the specific TLD allows it.
