 There's an existing ticket for this, #19919.

 > 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.

 line, and give them a warning?

 We implemented this in 0.2.9 in #13953.

 Is this ticket now a duplicate? (Or now fixed?)
 We also have #17765 and #17782.
