IP Intelligence
PTR, ASN, and Spamhaus RBL checks for public IP addresses
About this tool
Check reverse DNS, Team Cymru ASN data, and Spamhaus ZEN listing for any public IP. Free, no signup. IP Intelligence runs in the browser on DevTools. There is no signup, and your input stays on this device unless the tool explicitly performs a live network lookup.
What this tool does not do
- IP Intelligence is a free in-browser utility, not a hosted API. It does not keep server-side history and is not a substitute for production verification in your own stack.
