IP Geolocation: How It Works

7 min read Intermediate

IP geolocation determines where an IP address is physically located. Understanding how it works is important for content delivery, compliance, and choosing the right IP addresses for your needs.

How IP Geolocation Works

Geolocation databases map IP address ranges to physical locations using multiple data sources: RIR allocation data, ISP information, user feedback, and active network probing.

When you connect to a service, it looks up your IP in these databases to estimate your location.

Accuracy by Location Type

Geolocation accuracy decreases as precision increases.
