Comment:

 I don't think this is a dependency of #17901 any more - their
 implementation transparently redirects connections to 127.0.0.1 to the
 non-loopback, potentially public, jail IP address.

 Finding loopback addresses doesn't help with that if there are none.

 However, if the jail has a non-127.0.0.1 loopback address that's still in
 127/8, #17991 would help with that.
