Watch how easy it is to query Geolocation data using simple DNS lookups
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.
