	Its not quite that simple folks.  The reason this particular
	block is reserved has some real technical merit, while the 69/8
	muddle is strictly due to ISP negligence.

	RFC 3330 got it wrong.  Anyone remember the "Martian List"
	from the 1970-1990's?  Trying to use the all-ones or all-zeros
	network for real traffic is not possible.  Pre CIDR it was
	not possible to use 192.0.0.0/24 or 192.0.255.0/24. (the same was
	true on -every- network boundary) With CIDR,
	those boundaries moved to 1.0.0.0/24 and 223.255.255.0/24
	e.g. only two reservered blocks instead of hundreds.  

	Simply having someonechange a DB entry or create an RFC will 
	not affect the installed silicon base.  Won't work.   
	APNIC is on the moral highground here.  They received damaged 
	goods without notification. IANA needs better technical clue.
