Comment:

 The old answer here is "you didn't set your Address line, so what did you
 expect?"

 I wonder if the new answer should be that we look at the IP address you
 used in your ORPort line, if present, and prefer that guess over the "ask
 for our hostname, then try to resolve it" heuristic.

 (That new answer is newly possible now that ORPorts can have IP addresses
 in them too.)

 That said, am I right that the {{{ORPort 192.0.2.1:443}}} syntax is bad
 news because it (maybe surprisingly) doesn't listen on 0.0.0.0, so e.g. it
 won't listen on localhost? If so I would argue that people who are trying
 to set their Address line by putting an IP address in the ORPort line are
 doing it wrong.

 I guess a much simpler first step could be to notice when the operator
 puts an IP address in ORPort or DirPort, but *doesn't* set their Address
 line, and give them a warning?
