No, and neither can anyone else... What's more is that they'll not use .0, .255, .1 (because apparently only routers are supposed to use that), .254 (who knows...)
There's actually a good reason for that. MS Windows (at least 2k3 server) will simply drop packets with a source address of .0 or .255 coming from the legacy class C space, this hit us with some Win 2k3 servers that for a bunch of stupid reasons needed to be connected to from natted hosts, and the next pool IP off the pile was a .255 address somewhere in 192.168.0.0/16. Took quite a while to diagnose as wireshark on the host wouldn't see the packet, but eventually we could verify the packet made it all the way to the machine. The fact that this may be UI in 2010 is very depressing, and a prime example of why there's no way the "class-E" space will ever be generally usable. Julien
