DNS Speed Test

Test public DNS resolvers right in your browser with live DNS-over-HTTPS (DoH) queries. In a few seconds, you can check response times, compare DNS servers, and find the fastest one for your network.

How to Find the Fastest DNS Server for Your Network

Testing your DNS speed is simple. Here's what you need to do:

1. Start the Test: Click Run Speed Test to start the live DoH test.
2. Wait for the Results: The tool tests more than 28 public DNS providers and displays their results.
3. Compare the Numbers: Check the table or chart to see the min, median, average, and max response times. You can also see the stability score.
4. Find the Fastest Server: Look at the Fastest for Your Location section to see the top three DNS servers for your connection.
5. Run It Again: If you switch networks or turn on a VPN, click Run Again to test the DNS servers again.

Key Performance Metrics Explained

Fastest DNS for Your Location

When the test ends, the Fastest for Your Location section shows the three fastest DNS providers among those tested during your current session.

DNS speed can change from one network to another. Your ISP, location, and network path can all affect the result. So, the fastest DNS server for you may not be the fastest for someone else.

How This DNS Speed Test Works

The tool sends DNS-over-HTTPS (DoH) requests from your browser to more than 28 public DNS servers. These include popular providers such as Cloudflare, Google, Quad9, OpenDNS, and AdGuard.

The tool measures how long each DNS server takes to respond. It then uses these results to compare the servers and show you which ones responded fastest.

Why Test DNS From Your Browser?

Many DNS tests run from a server in a data center instead of your network. This means you don’t actually see the fastest DNS server for your network and location.

This tool runs DNS-over-HTTPS tests from your browser to measure response times over your current connection. Here are the main benefits.

• Test your own connection: Results include the network path between your device and the DNS server.
• No software needed: You don't need to download or install anything to use our browser-based DNS speed test.
• Easy to repeat: You can easily run the test again whenever your network changes.
• See more than speed: The tool also shows different response times and successful queries. So you can choose the most reliable DNS provider.

Why DNS Speed Matters for Your Network

When you open a website, DNS helps find the server that hosts it. Your device needs this information before it can connect to the website.

Changing DNS will not make a 100 Mbps internet connection download at 300 Mbps. It can, however, reduce the time spent waiting for DNS lookups. A faster DNS server may make websites start loading a little sooner.

Practical Ways to Use This DNS Speed Test Tool

Here are some practical ways to use our DNS speed test tool.

• Choose a DNS server: Compare popular DNS providers and see which one responds fastest on your connection.
• Check slow browsing: If websites take too long to start loading, compare your current DNS with other providers to see if DNS is the issue.
• Set up your router: Test DNS providers before adding their DNS addresses to your router.
• Check a new network: If you change your ISP, move to a new network, or use a VPN, run the test again to compare the results.

Frequently Asked Questions

What is a DNS Speed Test?

A DNS Speed Test checks how quickly different DNS servers respond to requests from your network. It helps you compare public DNS providers and find fast options for your connection.

How does this tool measure performance?

The tool sends live DNS-over-HTTPS (DoH) requests from your browser to public DNS servers. It records their response times and shows the min, median, average, and max results.

Why do DNS speeds vary by location?

DNS speed can change based on your location, ISP, network path, and distance from the DNS server. This is why two people can get different results from the same DNS provider.

Will changing DNS make my internet faster?

Changing DNS will not increase your download or upload speed. It can reduce DNS lookup time, which may help websites start loading faster.

What's the difference between Median and Average speed?

The median is the middle result from the test. The average adds all the results together and divides them by the number of tests. 

The median can be useful when one unusually slow result affects the average.

Does running this test change my router or device settings?

No. The test only sends DNS requests to measure response times. It does not change your router, operating system, or network settings.
