SecurityTrails on a Mac
Historical DNS, WHOIS and subdomain data (paid API) · Security Tools
SecurityTrails (Recorded Future) keeps the history of DNS records, WHOIS and subdomains. Use it on your own domains to find forgotten subdomains and old DNS records that still point somewhere; a dangling record is how a subdomain gets taken over. Plans differ in monthly queries. This pane reads this month's usage against the allowance and alerts before it runs out; record what you pay in the Plan & Cost card.
