A class B network is recognized by its network address, 145.11.0.0. The network address of its first subnet is 145.11.0.0 as well. Explain why identical network addresses for two networks (the main one and one of its subnets) won't create any ambiguity. List the network address of subnet 15 if the class B network in the previous part has been divided into 32 subnets (subnet 0 to subnet 31). Also specify the address range of subnet 29. Finally, list the direct broadcast address of subnet 31 and the network address of subnet 14.
