WHOIS is the name of search tool that lets you find the certain information, and is publicly accessible. When you create a website, you register a domain name. Once you register the domain name, ICANN requires you to list down that information in a public database. It is the information available to anyone who uses WHOIS protocol, and anyone can look up the owner of that domain name. WHOIS database requires mailing address, contact number, and email address of domain owner, which is publicly available.

They influence registrars to take reasonable step or expel any customer who lists down inaccurate ownership details in the database. As a domain owner, you need to fill correct ownership details for domain you want to register. Moreover, ICANN also provides an option of WHOIS inaccuracy complaint form. It allows internet users to submit reports to ICANN-accredited registrars regarding incomplete or inaccurate WHOIS data. They analyze each report submitted to them. And, then they take action after report status is deemed valid or either invalid.
