DNS Leak Test giving different results
« on: October 01, 2022, 06:29:36 pm »
I ran the Extended test from Chromium and it found 1 Comcast server as my DNS. I ran the same Extended test from Firefox and it found 3 Cloudflare servers as my DNS.


Why would the results be different when I am running them simultaneously from the same machine?

Because Firefox is not using your computers resolver but just the CloudFlare DNS servers via DoH directly.

It renders your IDS useless....

Block it and it will revert to port 53 and use your local DNS resolver
