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.
