Feature request: show transport protocol in dig(1) footer
Description
I just stumbled over dig(1) using TCP by default for ANY requests, which is documented, but in the course of time I somehow forgot about that. Carsten came up with an idea I'd like to endorse: add the Transport protocol to the footer of dig(1)'s output.
Request
What we'd like to see is the transport dig(1) has ultimately used for the query, somewhat along these lines:
;; Query time: 589 msec
;; SERVER: 172.22.1.8#53(172.22.1.8)
;; TRANSPORT: TCP
;; WHEN: Thu Oct 29 12:40:17 UTC 2020
;; MSG SIZE rcvd: 53The transport would likely be one of TCP, UDP, DoT, or DoH.
