Comment:

 I think this is a feature, not a bug.

 If an authority votes for its own IPv6 address, and it's the only one to
 do this, then its IPv6 address will always be in the consensus, even if
 it's actually unreachable. (A single IPv6-voting authority can determine
 an IPv6 address by voting for it.)

 When we make IPv6 mandatory on authorities, and change the consensus
 method so IPv6 votes are a simple majority, then we can fix this issue.
