Comment:
The IPv6 equivalent of an IPv4 /32 is a /64. We could have auths
reject multiple (more than AuthDirMaxServersPerAddr) IPv6 OR ports
with matching upper 64 bits. While the general abundance of IPv6
addresses might make this a bit toothless it shouldn't hurt.
Note that clients are not using IPv6 OR ports by default yet.
Moving to 0.2.4.x-final -- 0.2.3 dir auths don't handle IPv6 OR ports.
