Our 5 Steps to Achieving Unmatched IP Data Accuracy
While all IP data providers begin with the same foundational sources — Whois records and geofeeds for basic information — they stop after basic analysis and cross-referencing. IPinfo implements three additional, advanced phases of analysis.
At the heart of our process is our proprietary global probe network, which has mapped every IP address on the planet. This unique approach delivers an unmatched level of accuracy that sets our data apart.
Collect & Clean
Like all IP data companies, we collect starting data from multiple sources to build the foundation.
Learn
Our proprietary algorithms analyze 20+ terabytes of data each day to clean and score each IP record.
Establish Ground-Truth
900+ global Probe Servers triangulate and map every IP in real time with ground-truth precision.
Validate
Our purpose-built hint engine analyzes 400Bn IP measurements each week to validate all data.
Update
Our data is constantly updated, ensuring that our users always have the most reliable, high-quality data.

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.

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.
