It seems efforts related to IP address specific policies are likely
doomed by the sheer size of the address space, and to be pedantic, ARP
has been replaced with multicast neighbor discovery which dramatically
reduces the overall traffic involved. Secondly, doesn't Secure Neighbor
Discovery implemented at layer 2 fully mitigate these issues? I too
would be interested in hearing from Radia and Fred.
