Unrivaled data accuracy
Verified IP Accuracy. Not Estimates.
Most IP providers stop at noisy Whois and geofeeds. IPinfo goes further. We don’t just collect IP data — we verify it, validate it, and engineer it for developers.
They guess. We measure. And that makes all the difference.
Step 1: Collect & Clean
Like most IP data companies, we aggregate raw IP data from multiple sources as a starting point.
Step 2: Learn
Our proprietary algorithms then score and filter 20TB+ of IP data daily to measure accuracy and confidence.
Step 3: ProbeNet Ground Truth
1000+ live PoP’s map IPs around the world in real time, delivering unmatched ground-truth accuracy.
Step 4: Validate
A custom hint engine runs 400B+ weekly checks to verify and confirm every signal for total accuracy.
Step 5: Continual Updates
IP’s change continually… so our data refreshes daily to keep every lookup accurate, stable, and production-ready.
