Logging with Unencrypted DNS, DoT and DoH

[Richard T.A. Neal]

Hi Ralph,

I don't believe this is presently possible but it's being considered for future development. Please see the following Issue Ticket for more details:

Best,

Richard.

Subject: Logging with Unencrypted DNS, DoT and DoH

Hello,

BIND 9.18.7
RHEL 8.10 (Oopta)

I am being asked if it is possible to differentiate the percentage of queries coming into a server that are unencrypted, DoT and DoH.
Example: For a given 24 hours, 50% were 53, 25% were 853 and 25% were 443.
I cannot find a difference in the query logs to show how the query came into the server. My only thought at the moment is to run 'tcpdump' on all of the servers and script something.
Is there some way that I just have not found within BIND?
My apologies if this has been asked previously.

Thank you,
