Mozilla publishes DNS over HTTPS experiment results

1 min read

Mozilla released the Nightly version of Firefox earlier, introducing the DNS over HTTPS (DoH) feature. It invited users to test encrypted domain name resolution called Trusted Recursive Resolver (TRR). Today’s DNS resolution is usually not encrypted and insecure. Using the DoH will make DNS resolution more secure.

Now, Mozilla has published the experimental results of DNS over HTTPS. About 25,000 users participated in the experiment, generating more than 1 billion DoH transactions.

 

The results show that for non-cached DNS requests, DoH has little impact on performance, and most requests are only six milliseconds slower, which is an acceptable price for data security. The experiment is over, and the Nightly version of the user can still be manually enabled.
