I think he has a dynamic IP address which is why, according to pasted
torrc, the used config is:
`Address Address my.dynamic.dns.url`
This is a perfectly normal and accepted use-case. I think this is why it
complained about not being able to find an IPv6 address, because it was
resolving a hostname instead of parsing an IP address and most probably
it did not find any AAAA record.
Anyway, IPv4Only in the ORPort line is the right config for this
use-case (where you don't have any IPv6 thus don't want to use IPv6
auto-discovery), as David said, most annoying bugs regarding IPv6
auto-discovery were fixed. So the suggestion to use IPv4Only in torrc
line is not a workaround a bug or misbehavior or something, it is a
corrected configuration parameter (as per manual instructs) and should
stay like this even in 0.4.5.7 of course.
I only find this log message unclear:
[notice] Unable to find IPv6 address for ORPort 9001. You might want to
specify IPv6Only to it or set an explicit address or set Address.
I think it means "... You might want to specify *IPv4Only* to it or set
it to an explicit address or set configure Address."
Is this suggestion correct David? I mean, it complains about not being
able to find an IPv6 address (so most probably there is none to find)
but it requires you to specify IPv6Only -- impossible, since you don't
have any IPv6. I don't think it makes sense, or are my thoughts too
mixed up? If yes, could you do a fast PR since it's something trivial or
should I file a ticket on gitlab? This should make it in 0.4.5.7 if yes
