Perhaps I missed something in an RFC somewhere, but I believe those bits only have meaning locally on an Ethernet LAN. They have no meaning when used on non-Ethernet networks, for instance POS or on a Loopback. If someone wanted to use them for a /128 virtual for their web site for instance that would be ok. Or, turning that around, if you assume an IPv6 address is part of a /64 on an Ethernet network, you have made a false assumption. -- Leo Bicknell - bickn...@ufp.org - CCIE 3440 PGP keys at http://www.ufp.org/~bicknell/
