Everything you need to know about IPFly’s API service, data, and billing.
General Questions
What is IP geolocation and how does it work? +
IP geolocation determines the physical location of an IP address. Our system uses a combination of proprietary data, public databases, and machine learning to map IPs to geographic locations with high accuracy.
How accurate is your geolocation data? +
City-level accuracy is approximately 95–98% for most regions. Country-level accuracy exceeds 99%. Accuracy varies by region and depends on local internet infrastructure and data availability.
What's the difference between free and paid plans? +
Free plans include basic country-level geolocation with daily limits. Paid plans offer city-level data, threat intelligence, higher accuracy, more requests, VPN detection, and dedicated support.
How often is your database updated? +
Our geolocation database is updated daily with new IP assignments and location data. Threat intelligence feeds are updated in real-time as new threats are identified.
Technical Questions

Threat Intelligence
What threat intelligence data do you provide? +
Our threat intelligence includes VPN/proxy detection, Tor exit node identification, cloud provider detection, relay detection, and proxy type classification.
How accurate is your VPN detection? +
Our VPN detection accuracy exceeds 98% for known VPN services. We continuously update our detection algorithms to identify new VPN providers and techniques.
Do you detect residential proxies? +
Yes, we have advanced detection methods for residential proxy networks and other sophisticated anonymization services that traditional detection might miss.
