How it Works
How It Works
This tool measures the response time (latency) of popular DNS servers by sending DNS queries directly from your browser. It helps you find the fastest DNS for your location and network, improving your browsing speed and privacy.
- Uses browser-based DNS-over-HTTPS (DoH) queries for accuracy and privacy
- Tests multiple well-known DNS providers (Cloudflare, Google, Quad9, OpenDNS, etc.)
- Displays results in a sortable, color-coded table and interactive chart
- No data is sent to our server; all tests run in your browser
Technical Details
Technical Details
The DNS Speed Test uses the DNS-over-HTTPS (DoH) protocol to measure latency. It sends multiple queries to each DNS server and calculates the average response time. Results are visualized for easy comparison.
- Uses the
fetchAPI to send DoH queries - Measures round-trip time for each query
- Supports both IPv4 and IPv6 DNS servers
- All processing is client-side for privacy
