[Pdns-users] Will DoT disappear in favor of DoQ for recursor to auth?

No plans.

Currently, Recursor does not support outgoing DoQ. If/when we start
supporting outgoing DoQ it would not *imply* dropping outgoing DoT.

BTW, lookingt at https://talk.desec.io/t/dot-support-status/502:
when I grep for desec I see this:	desec.io.	6	Good	2022-09-21T15:35:38	desec.io.	5	Good	2022-09-21T15:37:32
2607:f740:e00a:deec::2	desec.io.	6	Bad	2022-09-19T15:35:35
2607:f740:e633:deec::2	desec.io.	5	Bad	2022-09-19T15:35:42

So it seems DoT is only supported on v4. Also not that the domain
listed for an IP is the first name the lead to a DoT probe. Other
names might be served by the same IP.
