 Replying to [comment:6 nickm]:

 than the self-testing issue?

 Is it possible that you're mixing up #6362 and #6363 (Make directory
 authorities vote on "a" lines in consensus network status
 documents). The latter lacks support for microdescriptors.

 > Also, is there any risk of unintentionally getting an ipv6 address when
 you didn't mean to?  If so, this patch is a little risky: it might make a
 working node accidentally advertise a non-working IPv6 address, thus
 getting the 0.2.4 authorities to mark it as down.

 At the moment, no. Advertising an IPv6 address requires not only that
 what's given in an ORPort option parses into AF_INET6 but also that it
 passed !tor_addr_is_internal() with 'for_listening==0, i.e. is not
 "[::]" (see #5146). This might change when we fix #5940 (which needs
 design love btw).

 A related question is how we should treat "ORPort 4711" on a system
 with an IPv6 address. This is unresolved in prop186 -- should the
 'AllAddrs' option be on by default?
