Benchmark DNS resolver performance across multiple providers and geographic locations. Compare response times to find the fastest, most reliable DNS resolvers for your domain.
DNS benchmarking measures the performance of different DNS resolvers when querying your domain. Response time — the time between sending a DNS query and receiving the answer — directly impacts page load speed, application responsiveness, and user experience. By benchmarking resolvers like Google DNS, Cloudflare, Quad9, and your ISP's resolver, you can identify which provides the best performance for your specific domain and geographic audience.
DNS resolution is often the first step in loading any web page. A slow resolver adds latency before the browser can even request the actual content. Fast DNS can shave 50-200ms off initial page loads.
Assuming the default ISP resolver is optimal, not considering geographic proximity, only testing from one location, and not re-testing after DNS infrastructure changes or during peak traffic hours.
Type the domain to benchmark resolver performance against.
We send DNS queries from multiple resolver locations simultaneously.
Response time is measured for each resolver and record type.
See ranked results with fastest and slowest resolver highlighted.
Benchmarks against major public resolvers including Google DNS, Cloudflare, Quad9, OpenDNS, and your ISP's resolver. See how each performs for your specific domain.
Resolvers are tested from multiple geographic locations. A resolver that's fast in the US may be slow in Asia — see the full global picture for your audience.
Measures query response time in milliseconds with statistical breakdown including min, max, average, and standard deviation across test runs.
Separates benchmark results by record type (A, AAAA, MX, TXT, NS). Different resolvers may cache or route different record types with varying efficiency.
Tracks timeout rates and failure percentages per resolver. A fast resolver that frequently times out is worse than a slightly slower but more reliable one.
Based on response time, reliability, and geographic proximity, we highlight the optimal resolver configuration for your domain and audience.
Automate DNS benchmarking, track resolver performance over time, detect degradation, and get alerts when response times exceed thresholds.
