Sidetrack: I really wish OS vendors would support DNS over TLS (and maybe DoH, I just prefer the former).
I understand that on a LAN the router is typically acting as the DNS server but I don’t see why the OS couldn’t be smart enough to automatically detect DNS over TLS on the standard port when overriding the DNS settings manually.
I think you can do that right now on Linux, this Quad9 article describes it working with
systemd-resolvedTypo, you mean DoH at some point in your comment.
Corrected, thanks 👍
I can’t speak to Android but all of those require running some DNS recursive resolver locally then pointing the OS resolver to it. While I do that already, it doesn’t really address the issue I’m getting at: the OS doesn’t natively support it.
On macOS/iOS I use a
.mobileconfigfile to point to my Dockerized DNS over TLS resolver in the cloud and it works great, but why do I need to do that rather than use the “normal” DNS preferences? Command line tools still revert to the DHCP DNS server so on macOS I run unbound to take care of that.For Linux, I’m mainly running a Raspberry Pi on Alpine Linux with unbound as well; it works great for DHCP clients that get pointed to it but (especially if this were some company LAN) all the DNS queries are still going over the LAN unencrypted.
