The problem I kept hitting: most IP lookup tools are either paywalled after a handful of queries, return stale data, or both. I wanted something I could hit from a script at 2am without worrying about rate limits or reaching for a credit card.
How it works:
- Enter an IP and get back geolocation (country, region, city, coordinates, timezone), ISP/org data, and a threat assessment. - The threat data is cross-referenced against 24+ blacklist sources, refreshed every 4 hours. - Nearly 300k blacklisted IPs indexed currently, growing with every cycle. - Free API — register for a key and integrate it into whatever you're building.
The stack is PHP on Apache/Ubuntu with MySQL and Redis. Nothing exotic.
It's free and will stay free. No freemium trap, no "enterprise tier coming soon". The more people using it and feeding back, the better the intelligence gets for everyone — it's a network effect thing.
I'd appreciate any feedback on the tool, the API, or the data quality. Happy to answer questions about the architecture or the threat sources.
