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.

The data is available right away, and you can try it on the website or use the API. The plans are flexible and can be adjusted to our changing request volumes. Most competitors, when it comes to their IP privacy data, require you to commit to a larger response – some back-and-forth with emails, going for a more expensive plan right away. And that's something we didn't want.
The implementation was absolutely flawless. Getting set up with IPinfo was very easy. From researching providers, to implementation and testing of the API, it took a few hours maximum.
Geolocation is a really important point for our customers. When an account logs on and is involved in suspicious activities that look like security risks, it’s very important to be able to identify where that person normally logs on versus the location of the suspicious activity. It’s a vital piece of context to make decisions on how to respond to that particular area of risk.
