32bit IDs

	A lot of protocols use 32bit IDs
	32bit IDs = management headaches, scalability limitation

	What is the domain of uniqueness?
		OSPF - within an AS
		BGP - worldwide uniqueness needed

	How wide does ID need to be?
		128bit - global IPv6 address can be used
		64bit - EUI64 maybe? (not guaranteed to be unique)
		64bit - 32bit AS number + 32bit serial (management headache)
		32bit - insufficient (32bit AS numbers)
