Assuming that the cluster / public network has not been explicitly set,
can't we bind in such a way that it will accept either, i.e., bind an
IPv6 socket and setsockopt IPV6_V6ONLY = 0?
Most network daemons these days seem to be moving towards that trend. We
would just need to check for non-IPv6 capable IP stacks (seriously...?)
before the bind, in which case it's a moot point anyway.
