	actually, its pretty close.  slightly older view of
	IPv6 has the top/left 32 bits as fixed, the bottom
	64 bits as fixed.  the second 32 bits as the delegation
	space for which CIDR applies....  which is the same
	issue as flat routing of the IPv4 space as /32s.
	Newer versions of address architecture have "freed"
	up the constraints on the left hand side...
