Resolver speed is not universal. The fastest DNS for one city, mobile carrier, or ISP may be slower somewhere else. That is why benchmark data matters more than brand recognition.
Comparison table
| DNS | Provider | Privacy | Speed |
|---|---|---|---|
| 1.1.1.1 | Cloudflare | High | Very Fast |
| 8.8.8.8 | Google Public DNS | Medium | Fast |
| 9.9.9.9 | Quad9 | High | Fast |
| 1.1.1.3 | Cloudflare Family | High | Fast |
Detailed explanation
Public DNS speed depends on three things: how close the provider is to you, how stable the route is between your ISP and the resolver, and how efficiently the resolver caches frequent answers. Cloudflare usually scores well on all three, which is why it appears in so many “fastest DNS” discussions.
That said, some networks route more efficiently to Google or Quad9. In business environments, security filtering or policy controls may matter more than the last few milliseconds. If you want a closer look at Cloudflare’s resolver, read Is 1.1.1.1 the best DNS?.
What to measure
- Average latency: how quickly the resolver answers a request.
- Jitter: how consistent those answer times remain over repeated lookups.
- Timeouts: whether the resolver occasionally fails or responds too late.
- Cache behavior: whether common lookups stay fast under normal usage.

How to choose
Start with two or three candidates, run a benchmark at the same time of day you actually use the network, and keep the fastest stable option as primary. A practical setup is a fast primary resolver and a well-known secondary resolver such as Google or Quad9.
