DNS Benchmark
Compare DNS resolver response times in real time. Find out which is fastest from your location — Cloudflare, Google, Quad9, OpenDNS, and more.
How DNS Speed Affects You
Every time your browser loads a new hostname, it performs a DNS lookup first. If you visit 20 different domains loading a single page, that's 20 DNS queries. With a fast resolver, each takes 5–20ms. With a slow one, 100–300ms. The difference compounds.
Switching to a faster DNS resolver is one of the easiest performance wins available — takes 30 seconds to configure, no software to install.
How to Change Your DNS
- Windows — Control Panel → Network → Adapter → Properties → TCP/IPv4
- macOS — System Preferences → Network → Advanced → DNS
- iOS — Settings → WiFi → (your network) → Configure DNS
- Android — Settings → Network → Private DNS → enter dns.cloudflare.com or dns.google
- Router — Set at router level to apply to all devices
Frequently Asked Questions
Cloudflare (1.1.1.1) and Google (8.8.8.8) are consistently fastest globally. The winner depends on your location and ISP. This benchmark tests from your browser's perspective, giving you a real result for your specific network.
1.1.1.1 is Cloudflare's free public DNS resolver. It's privacy-focused (no query logging), fast (often <5ms globally), and supports DNS-over-HTTPS and DNS-over-TLS. The companion 1.0.0.1 is a secondary resolver.
Yes, especially for uncached lookups. DNS resolution happens before any HTTP request begins. Shaving 50-100ms off each DNS query improves time-to-first-byte for every new domain you visit.
DNS results include caching, network jitter, and server load variability. We run multiple queries and show median times for accuracy. Results reflect performance from your location at this moment.
