	I meant getAllByAddress. There is no getAllByName. Just a typo.

	You're knowlege of the protocol is getting in your way. All the query says is "I'm
	looking for a name with type 0x00 at host 10.0.100.114 without scope". That's it.
	The response in this case was "Nope, no name with type 0x00 at 10.0.100.114
	without scope, sorry".

	It is. It does a NODE_STATUS_REQUEST using the wild card "*\0\0\0\0\0..." name
	with a hex code of 0x00 and type of NBSTAT to port 137 of the specified IP. If no
	response comes back you get:

	UnknownHostException: no name with type 0x00 with no scope for host 10.0.100.114

	What's the problem?
