Yes.
As we talked on IRC about the private ranges, you told me to post my 
results here.

I'd recommend to treat the following subnets as invalid:

Subnet			Description
10.0.0.0/8		private
127.0.0.0/8		loopback
169.254.0.0/16		link local
172.16.0.0/12		private
192.0.2.0/24		testnetwork (documentations)
192.168.0.0/16		private
224.0.0.0/4		internet IPv4 multicast area

see RFC3330 and its references.
