Weird but cool(?) quirk that tripped me up on testing something just now.

I set my DNS (in /etc/resolv.conf) to 9.9.9.11 (it's quad9 with EDNS0 ECS support) and my Chrome seemingly auto upgraded it to DoT/DoH. Since the ECS that came back was... IPv6.

I mean, nice improvement, but also not what I was looking for when doing this for debugging reasons...
