What is the fastest DNS server?
Compare the fastest public DNS servers, including Cloudflare, Google, and Quad9, and learn how to test speed on your network.
DNS Benchmark tests latency, jitter, and availability of the top DNS servers — Cloudflare, Google, OpenDNS, and more — directly on your Android or iPhone. Compare results, find the fastest DNS, and improve your connection in seconds.
A complete tool to understand, compare, and improve DNS performance on your device.
Measures the response time of each DNS server with millisecond precision. Know exactly how long each resolution takes.
Analyzes latency variation between consecutive requests. High jitter causes instability in video calls and online gaming.
Tests DNS over HTTPS (DoH) servers for more secure and private connections. Compare performance between classic DNS and DoH.
Saves results from every test so you can track progress over time and compare different configurations.
Tests Cloudflare, Google, Quad9, OpenDNS, AdGuard, and many more at once. Find which one works best in your region.
Generates a full report with P50, P95, P99, average, and availability for each server tested. Ready to export and share.

DNS Benchmark is a mobile app that tests DNS latency, jitter, and availability directly from your Android or iPhone. It compares public DNS providers on your real connection so you can choose the fastest and most stable option for your network.
DNS latency is the time a DNS server takes to answer a lookup request. Lower DNS latency helps websites, apps, and streaming services start connections faster because the IP address lookup completes sooner.
DNS jitter is the variation between consecutive DNS response times. Lower jitter means more stable results, which is important for gaming, voice calls, and streaming sessions that depend on predictable network behavior.
Changing DNS does not increase your raw download bandwidth, but it can reduce the time needed to resolve domains and open new connections. That often makes browsing, app launches, and video startup feel faster, especially if your current DNS provider is slow.
Yes. DNS Benchmark is available for both Android and iPhone, and the website links to both app stores. The app is built to benchmark DNS from the mobile connection you are actually using at the moment.
Yes. DNS Benchmark is especially useful for gaming and streaming because it exposes both latency and jitter, the two metrics that most affect perceived responsiveness and stability. Once you identify the best resolver on your connection, you can apply it on your device or router.
Yes. DNS Benchmark is free to download and use. Optional paid upgrades may unlock extra capabilities such as advanced analytics, custom DNS management, or visual themes depending on the platform version.
