How does ipinfo.io determine IP geolocation accuracy?

Hi everyone,
I’m curious about the methods ipinfo.io uses to determine the accuracy of IP geolocation data. Are there specific data sources or algorithms involved? How often is the location data updated, and what factors affect precision?
I’d love to understand more about how this works behind the scenes.

We don’t rely on a single source, but instead combine multiple signals and continually refine their data.

We gather latency and network measurements through the Probe Network, IP allocation data from regional internet registries (RIRs) and WHOIS, BGP routing data that shows which networks are announcing specific IP ranges, and anonymized ground truth signals. We also use reverse DNS naming patterns and known cloud or hosting region info to improve precision.

Are there specific data sources or algorithms involved?

There are plenty of specific data sources and algorithms to help us.

How often is the location data updated, and what factors affect precision?

Our IP geolocation is updted daily.
