Reserved class A's you should NEVER see traffic from (at least until they start getting desperate for IP's):
0.0.0.0/255.0.0.0 1.0.0.0/255.0.0.0 [...]
Where do you derive that information from? Right now some of the networks still belong to IANA (--> unused), but how can a system administrator be
sure that the network won't be opened within the next few days? In worst case I'd deny access to my network for 254^3 IPs.
updates concerning reserved IANA netblocks can be found on http://www.iana.org/assignments/ipv4-address-space . Take a look at it every month or so... All the address blocks marked as "IANA - Reserved" should be blocked on the FW; no legitimate traffic should come from there.
