Q: Subnetting
Submitted By: thaJack, 252 days, 10 hours, 39 minutes ago
Is a Class "A" network always a class "A" network? For instance, if I take the network 10.0.0.0/8 (a class "A" network) and subnet it so that it is 10.0.0.0/24, is it still class "A" or is the network now a class "C"?
I would say a class "C" since the classes are originally created to distinguish the number of hosts available on a network, right?
Same goes with the reverse. If I take 192.0.0.0/24 and change it to 192.0.0.0/8 (granted I can really only do this internally and as long as it always stays disconnected from the rest of the world) it does become class "A", correct?
My point is this... does the class change with the mask?

No it's still class A

In a Class A address, the only constant digit is the first octet. The rest are variable. Class C only allows the last octet to be changed.
