Comment (by teor):
This flag only applies to IPv6.
And it will not be shown, as long there are a majority of ReachableIPv6
authorities voting for each and every consensus.
Here's why:
* relays with unreachable IPv4 ORPorts are always marked as not Running,
and excluded from the consensus. Their addresses never appear in onionoo's
unreachable_orports field, because they are never included in the
consensus
* if a majority of voting authorities have IPv6, IPv6 ORPorts are treated
the same as IPv4 ORPorts.
* if a minority of voting authorities have IPv6, some IPv6 addresses may
appear in unreachable_orports, but the numbers will be small (see
Karsten's graphs on #23761)
Reference:
https://metrics.torproject.org/onionoo.html#details_relay_unreachable_or_addresses
So if one of the 5 IPv6 authorities stops IPv6 or goes down, this feature
will be very useful.
Otherwise, it won't get used at all.
(We didn't know this until after #23761, and more authorities adding IPv6,
and the consensus-health ReachableIPv6 feature.)
