A free DNS speed test that compares Cloudflare, Google, Quad9, AdGuard and more — measured right in your browser. See which resolver answers quickest, then switch in a couple of minutes with our setup guides.
Balanced accuracy — 8 lookups per resolver. Tests 7 browser-accessible resolvers.
Runs entirely in your browser. We measure how quickly each resolver answers a fresh lookup over encrypted DNS-over-HTTPS — no downloads, no account, nothing stored.
Every time you open a website, your device first asks a DNS resolver to translate the domain name into an IP address. That lookup happens before anything loads — so a slow resolver adds a small delay to every new site you visit.
A DNS speed test measures how quickly different resolvers return that answer. Comparing several public DNS servers side by side shows you the fastest DNS for your location and connection, which is often quite different from the default your internet provider assigns.
DNS speed test
A tool that measures how fast DNS resolvers answer a domain lookup, then ranks them so you can pick the quickest and most reliable option for your connection.
Think of DNS as the internet's address book. This test times how long each resolver takes to find an address, using median and jitter — not a single lucky lookup — so the comparison is fair and repeatable.
Three steps, run automatically for every resolver.
We open an encrypted DNS-over-HTTPS connection to each resolver and run a throwaway lookup. These warm-up requests pay the one-time setup cost and are excluded from the result.
We request several unique, uncacheable hostnames and time how long each resolver takes to answer. Random names force a real lookup instead of a cached shortcut.
For every resolver we calculate the median, average, minimum, jitter, and success rate — then rank them so the fastest, most consistent option is obvious.
DNS resolution is the first thing that happens when you visit a site, and it repeats for every new domain a page pulls in — images, scripts, ads, and trackers can each trigger a lookup. A quicker resolver trims milliseconds off each one, so pages start rendering sooner and browsing feels more immediate.
The effect is most noticeable on the first visit to a site and on connections with high latency to the default resolver. Once a name is cached, later lookups are instant regardless of provider.
The best-known public resolvers, with their addresses and what makes each one distinct. Run the test above to see how they perform from your connection.
Cloudflare
The fastest major resolver on most connections, with a strong no-logging privacy stance and no default filtering.
1.1.1.1 1.0.0.1 A globally distributed, extremely reliable resolver. Uses EDNS Client Subnet, which helps CDN routing at a small privacy cost.
8.8.8.8 8.8.4.4 Quad9 Foundation
A security-first non-profit resolver that blocks known malicious domains and keeps no source-IP logs.
9.9.9.9 149.112.112.112 Cisco
A long-established resolver with phishing protection and optional content filtering, backed by Cisco's network.
208.67.222.222 208.67.220.220 AdGuard
Blocks ads, trackers, and malware for every device on your network without installing anything.

Weigh four things, roughly in this order:
Low, steady latency reduces the pause before a match server or patch host resolves. Consistency (low jitter) matters more than the raw minimum.
See the pickA fast resolver shortens the time before a video app connects. It will not raise your bandwidth, but it can make apps feel snappier to start.
See the pickSome resolvers keep no personal logs and refuse to share your subnet. If privacy is the priority, that stance matters as much as speed.
See the pickThreat-blocking resolvers filter known malicious domains before they load, adding a quiet layer of protection for the whole network.
See the pickFamily resolvers block adult content and malware at the network level, covering every device without extra software.
See the pickA DNS speed test measures how quickly different DNS resolvers answer a lookup — the step that turns a domain name like example.com into an IP address. This tool times that step for several popular public DNS servers from your own browser and ranks the fastest one.
Not your download bandwidth. A faster DNS resolver can shorten the brief delay before a website starts loading, which makes browsing feel more responsive. It does not change how many megabits per second your connection delivers.
It measures real browser-to-resolver latency over DNS-over-HTTPS from your connection, using warm-up requests and multiple randomized lookups to reduce noise. Because browsers cannot send raw DNS packets, it is not identical to a native benchmark — the methodology page explains exactly what the numbers mean.
It depends on where you are. Cloudflare (1.1.1.1) is frequently the fastest on residential connections, but Google, Quad9, and others can win in specific regions. The only reliable answer is to run the test from your own network — that is what this tool is for.
No. The test runs in your browser, we never store your browsing history or full IP address, and results stay on your device unless you choose to export or share them.
