IP Geolocation Over DNS

Lightweight geolocation data for IoT, satellite, and edge devices.
50-200 bytes per lookup vs 1KB+ for HTTP APIs

Archived hackathon project. The service is offline, and this site is kept for reference.

Example from when the service ran: dig TXT 8.8.8.8.rslvr.one → "US|United States|North America|NA|AS15169|Google LLC|google.com"

Recorded Demo​

This recording shows the service while it was live. The DNS service is now offline.

Minimal Bandwidth

50-200 bytes per lookup vs 1KB+ for HTTP APIs. Optimized for LPWAN, NB-IoT, and satellite connections where every byte counts. Ideal for battery-powered devices.

Universal Compatibility

DNS works everywhere — from ESP32s to legacy MCUs. No HTTP client libraries, no TLS overhead, no complex networking stack required.

Low Latency

Sub-second responses with no SSL handshake overhead. DNS queries are fast, reliable, and globally cached. Query 8.8.8.8.rslvr.one for instant location data.
