Reverse WHOIS is a type of query that allows users to identify domain names that use the same search term across WHOIS records. In effect, you can get a list of all domains owned by a specific person or organization using that search term.
You can use any registrant information that you have, including a person’s name, an organization’s name, an email address, a street address, a country, a postal code, and a phone number. You may also use a nameserver and WHOIS server as search terms.
