The main thing is that now no one has proposed to ban DNS-over-HTTPS…
So … people misusing DoH – a system that makes it impossible to block or see the traffic because you cannot block port 443 nowadays and where it is by design that the individual clients and not the operating system handle DNS requests?
DoH was a mistake.
DoH can be blocked while allowing other traffic. idk how, but the fortigate at my work has an active rule to block DoH.
Yes, it isn’t great how DoH traffic can’t be controlled well. Apps using DoH makes blocking ads unnecessarily more difficult. (DoT solves DNS encryption better imo.) HTTPS is already often unblocked and also difficult to analyze, but DNS is already used enough for malware communication.
