	A number of these prefixes were used in early documentation
	and as such were widely deployed by early adopters of IP.
	In the "bad old days" a large number of sites stood up IP
	networks in isolation, only interconecting -after- inital
	rollout was done.  Consider it as an early empirical trials
	with RFC 1918 space :)

	Based on the confusion, 192.0.2.0/24 was earmarked for 
	use in documentation... :)

	I know of no good reason why Juniper continues to flag these
	legacy blocks.
