Compare DNS lookup speed across 8.8.8.8, 1.1.1.1, and more.
The DNS Speed Test runs the same lookup (e.g. a domain name) against several public resolvers (e.g. Google 8.8.8.8, Cloudflare 1.1.1.1, Quad9, OpenDNS) and reports latency for each. Use it to choose a fast resolver for your network or device, to compare performance from your location, or to see if one resolver is slow or failing. Results depend on your location and network; running from a server gives one perspective; running from your browser gives your own. DNS latency adds to every new connection, so a faster resolver can improve perceived performance.
It varies by location and ISP. Run the test from your network; often 1.1.1.1 and 8.8.8.8 are among the fastest.
Depends on the tool. Client-side tests show your experience; server-side shows one region. Check the tool description.
Network path, firewall, or that resolver may be blocked or slow from your location. Try another resolver.
Faster is usually better for responsiveness. Also consider privacy and filtering (e.g. Quad9 blocks malware) when choosing.
On your device or router, set the DNS server to the chosen IP (e.g. 1.1.1.1). Your ISP's default will be replaced.
