How it works

Real tests, transparent scores,
actionable results

DNS Benchmark Pro measures real DNS-over-HTTPS performance from your browser — here is exactly what it does, what the output looks like, and why it matters.

Real results from a San Francisco test

Genuine output from a benchmark run in San Francisco, California — the live tool on the homepage produces exactly the same dashboard for your location.

DNS Benchmark Pro results dashboard: detected location San Francisco, California; Quad9 recommended as #1 with primary 9.9.9.9 and secondary 149.112.112.112 at 10.6 ms average, ±1.3 ms jitter, score 100/100; ranked benchmark results table below.
Ranked results with a clear recommendation. The dashboard detects the test location, crowns the fastest resolver — here Quad9 at 10.6 ms average with ±1.3 ms jitter and a perfect 100/100 score — and provides one-click copy buttons for the primary and secondary addresses.
Full-field latency chart showing response time bars for 31 responding DNS resolvers, fastest first, from Quad9 + ECS at the top to CIRA Shield Family slowest, color-coded green to red.
The full field, visualized. Every resolver that responded is charted fastest-first with color-coded response times, so you can see exactly how wide the gap is between the best and worst options on your connection.
Apply your recommended DNS panel: numbered Windows Settings app steps, a PowerShell Set-DnsClientServerAddress command with copy button, and an ipconfig /flushdns cache-flush command.
Setup instructions that fill themselves in. The recommended addresses are injected straight into numbered Windows/macOS steps, ready-to-paste PowerShell and Terminal commands, and the cache-flush command that makes the change take effect immediately.
The process

From one click to a faster connection in four steps

1

Detect your location

Your approximate location is detected (with graceful network-based fallback if you decline) so results are interpreted for where you actually are.

2

Probe 35+ resolvers

Timed, encrypted DoH queries run in parallel against every major public resolver — real requests over your real connection, not simulated numbers.

3

Score transparently

Latency, jitter and the 70/30 composite score are computed for the full field, with outliers discarded so a single slow packet can't skew a rank.

4

Apply in minutes

You get a ranked table, a #1 recommendation with copy-ready addresses, and step-by-step Windows and macOS guides — GUI and terminal included.

Why the best DNS matters

Four wins from one small change

Speed

Switching takes two minutes and costs nothing — yet it's often the single biggest browsing-feel upgrade available on an otherwise unchanged connection.

Stability

Video calls, cloud gaming and live streaming all depend on steady name resolution — a consistent resolver removes the random stalls users blame on Wi-Fi.

Security

Several ranked providers — Quad9, CleanBrowsing, Control D and others — block known malware and phishing domains at the resolver level, before a connection is ever made.

Reliability

Anycast networks run by major resolvers rarely go down — a well-chosen primary/secondary pair keeps name resolution working even when one provider has a bad day.
