	IPv6 doesn't use ARP.

	Privacy addresses are there primarially for machines that
	move between networks.  They prevent tracking of the machine
	by looking at the bottom 64 bits.  They also help somewhat
	when a machine stays on the same network. You don't know
	if it is the same person making connections or different
	people.
