A reverse WHOIS lookup is a means to retrieve all domain names containing your search term in their WHOIS records. With just a single piece of information, you can already retrieve relevant domains to get more insights for cybercrime investigations, market research, and threat hunting efforts.
Reverse WHOIS Lookup calls data from a WHOIS database that gets updated daily to ensure data accuracy and relevance.
Our WHOIS database contains more than 7 billion historical WHOIS records — a result of over a decade of data crawling.
You can choose any WHOIS record detail as a search term to pool all related domains.
Reports from Reverse WHOIS Lookup come with unique URLs, allowing you to share them with colleagues and relevant stakeholders easily.
