Introduction🔗
IP Intelligence returns geolocation, ISP, connection type, and network information for IP addresses. Use this data to adapt content delivery and assess requests.
Quick Start Guide - Get running in minutes.
How it works🔗
51Degrees uses an algorithm to identify IP network ranges and locations. The engine returns:
- Network data: ISP, organization, connection type
- Location data: Country, region, and city
- Ultra-low latency: Sub-millisecond with in-process in-memory deployment
- Performance-critical ready: Ideal for real-time servers, edge/load balancers, and high-load scenarios
- Deployment flexibility: In-process by default, with optional out-of-process or separate server deployment
Features include randomized coordinates and weighted results.
See technical specification for details.
Advanced features🔗
Coverage🔗
Data sourced from aggregating real device usage and multiple authoritative databases to provide comprehensive global coverage.
Coordinate randomization🔗
Coordinates returned for an IP address are randomized to within 1km of the original point, which keeps them precise enough for practical applications.
Weighted results🔗
Use weighted results to interpret location precision.
Device Detection integration🔗
Combine IP Intelligence with Device Detection to use network, location, and device data together.
Integration options🔗
Choose what fits your stack:
- On-premise: Run detection on your own servers.
- Cloud API: No infrastructure headaches and always updated, with a free plan and monthly or yearly paid plans.

Common use cases🔗
🎯 Targeted advertising🔗
Deliver location and device-appropriate advertising based on IP geolocation combined with device characteristics.
🌍 Content personalization🔗
Serve location-relevant content (news, language, pricing) while adapting to device capabilities and connection quality.
⚡ Performance optimization🔗
Anticipate network characteristics based on ISP and connection type to optimize content delivery and user experience.
🛡️ Fraud detection and security🔗
Detect click fraud, suspicious logins, and automated attacks by analyzing IP patterns, locations, and device combinations.
🚫 Geographical restrictions🔗
Apply rules that differ by country or region, such as for gambling, content licensing, or data protection law. Check LocationConfidence and IsVPN first, and ask the visitor for a precise location when the answer is unclear.
🗺️ Reverse Geocoding🔗
Convert coordinates to human-readable addresses using our Reverse Geocoding service.
