DNS Comparison Tool

Which public DNS resolver is fastest for you depends on where you are. This tool sends DNS-over-HTTPS queries from your own browser to eight popular resolvers and times the responses.

Tool status: Functional with limitations Works, but there are technical limits explained on the page.

Each resolver is queried 4 times from your browser. Nothing is measured until you press the button.

What this tool can and cannot do

Timings use encrypted DNS-over-HTTPS, which adds HTTPS overhead compared with classic DNS on port 53. The first query to each resolver includes connection setup and is shown separately. Some resolvers or networks block browser access; those are marked as unavailable rather than slow.

Data sources: Public DNS-over-HTTPS resolvers (queried by your browser)

Understanding the results

Look at the median "warm" time – it reflects normal use once a connection is open. Differences of a few milliseconds are not noticeable in everyday browsing.

Troubleshooting

  • To change DNS, set it in your router (affects every device) or in your operating system or browser's secure DNS settings.

Frequently asked questions

Is a faster DNS resolver a faster internet?

Only for the moment a website is first looked up. It does not change download speed. Reliability and privacy policy are often more important than a few milliseconds.
