    What range do addresses in a class A network have? I'm aware that for a class C network the range starts at 64 then 32, until working it's way down and that for a class b it starts at 64 and then when it reaches 0 starts at 128 and counts down.

    What happens with a class A address? Any help would be excellent

    Just remember with class A addresses its Network:Host:Host:Host for each octet in the IP Range.
    Once you get to VLSMs there will be no need for classes.
