Now, the classes of IP addresses is simple enough to understand --

But what about subnetting? When does one want to *really* use
two IP network address on the same cable? And what performance
advantages does this give you? Were does the netmask come it at?
Is subnetting just a nice admistrativia thing? Or does your local
enet board not receive the packets, period? Or is it the high
level software that ignores the packet? Does anything really ignore
anything?
