IP Address Geolocation

The process of determining the geographic location of an internet-connected device using its IP address.

NetworkingAlso called: "geolocation", "ip location"

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.
