The implementation is very easy and straightforward. The API is very concrete - features are highlighted and that’s it, nothing too fancy. I remember checking out some other services but none of them were easy to use or attractive from the economical point of view.

Frequently Asked Questions

  • Start by finding out how the IP data provider collects and validates location data. Check whether it includes timestamps, filters anonymized sources like VPNs and mobile carriers, and is based on active rather than static measurement. Once data reliability is confirmed, assess accuracy using:

    • Distance-Based Metrics: Median and mean distance error, plus 90th percentile error to spot outliers
    • Percentage Metrics: Percent of IPs located within 10km, 50km, or 100km of ground truth; city/region/country match rate
    • Coverage Metrics: Percent of IPs with results; confidence radius accuracy if available

    If ground truth isn't available, use physics-based methods like round-trip time (RTT) from multiple global locations. Speed-of-light limits help confirm whether an IP's reported location is physically possible. Independent verification tools like ping.sx or triangulation from multiple vantage points can reveal real-world location with high confidence.

  • Accurate IP data ensures content and ads are delivered only to approved regions. IPinfo helps enforce geo-fencing rules by providing precise geolocation information and detecting when location is being masked by an IP anonymization tool, details that are critical for adhering to compliance regulations.

  • Wasted impressions and reduced conversions are huge pitfalls when it comes to serving ads to the wrong audience. When geo-targeting fails due to inaccurate geolocation or undetected IP anonymizers, advertisers pay to show the wrong message to the wrong audience. IPinfo helps flag these anomalies and improve location accuracy upfront.
