The same. Separation would be unnecessary influence from a lower layer.=20

Useful for debugging. And no more.=20

Once a node is enough reachable (according to SLAen etc) to warrant
inclusion in DNS, the Internet Protocol number is just an indication
of which way to reach it. It is perfectly safe, and I do it all the
time. When my Internets break, I suffer. Of course. But that has
nothing to do with ipv4 vs ipv6.
