What this tool does
reverseips.com searches passive DNS observations for A and AAAA records whose value matches a public IP address. The free page shows a sample and the observed count when data is available.
- Security researchers - discover related infrastructure before deeper validation
- Domain owners - understand what passive DNS has seen on an address
- OSINT analysts - map infrastructure leads without treating shared IPs as proof of ownership
Method and limits
Data comes from Profundis.io passive DNS. A result means a domain was observed resolving to the IP at some point; it does not prove the domain is currently hosted there, owned by the same party, or reachable over HTTP. Empty results mean no match was returned for this free lookup, not that no domain ever used the address.
