5) Let N = number of network bits and H = number of host bits in an IPv4 address, we have N + H 32, since an IPv4 address is 4 Bytes, or 32 bits long. a) Make a diagram showing how many network and host bits there are in each class of IPv4 network. b) How many Class-A networks are there? How many IP addresses does each Class-A network contain? c) How many Class-B networks are there? How many IP addresses does each Class-B network contain? d) How many Class-C networks are there? How many IP addresses does each Class-C network contain
