Basic and intermediate network segmentation techniques
The first octet of an IPv4 classful network defines the class it belongs to. The subnet mask is irrelevant for determining the class; it's used only for subnetting or supernetting. For example, 200.0.0.0 with a 255.0.0.0 mask is a Class C network with 16,777,216 possible hosts minus two active ones. Correct?
