DNS IP History
The DNS IP History tool shows you all the IP addresses a domain or subdomain has ever resolved to, along with the first-seen and last-seen dates.
How to use it?
Enter a domain or subdomain in the search bar (e.g. google.com, api.stripe.com) and run the search. You can try a sample query.
The results show every historical A record with the time range during which each IP was active.
What can I use it for?
A common use is finding the original IP behind a CDN: if a domain now sits behind Cloudflare or Akamai, older records sometimes still expose the real server IP. It's also handy to see when a domain moved between hosting providers, or when an IP was added or replaced.
If you find an interesting IP in the results, you can search it in the DNS database to discover other domains that also pointed to it.
How many credits does it cost?
Each search you run spends 1 credit (see Credits). Results are paginated (30 per page).
