I saw this the other day and thought it’s worth sharing here. Currently Mozilla is partnering with Cloudflare while conducting experiments for their TRR to eventually enable it by default for all US Firefox users.
On the left is Cloudflare’s resolver for Firefox:
- DoH endpoint: https://mozilla.cloudflare-dns.com/dns-query
And on the right is Cloudflare’s “default/own” resolver:
- DoH endpoint: https://cloudflare-dns.com/dns-query
It appears Cloudflare logs more on their default resolver due to their partnership with APNIC. It makes sense now why Mozilla states in their blog post:
We’ve chosen Cloudflare because they agreed to a very strong privacy agreement that protects your data.
