IP geolocation maps IP addresses to physical locations using databases maintained by registries and ISPs.
Available information
- Country, City, Region: Approximate location (accuracy varies).
- Latitude/Longitude: Rough coordinates.
- ISP/Organization: Network provider.
- ASN (Autonomous System Number): Network operator identifier.
Use cases
- Content localization and language selection.
- Fraud detection (mismatched location and user profile).
- Access control based on geography.
- Threat intelligence and attack attribution.
Limitations
- VPNs and proxies hide true location.
- Accuracy decreases outside major cities.
- Mobile IPs may reflect carrier location, not user.
