[keeping the wide variety of potential IPv6 node behavior in mind] If RFC 6434 (IPv6 Node Requirements) is being followed then RFC 6724 (as RFC 3484-bis) MUST be followed. But older implementations may only support RFC 3484. Further, some implementations appear to do other things (as I believe OS X does, with its preferences for IPv4 vs IPv6). Tim
