Total number of addresses in the subnet: $2^{12} = 4096$ Broadcast Address: This is the last address in the subnet, obtained by setting all host bits (the last 12 bits) to '1' in the network address. This extends up to the next subnet boundary (10.5.128.0) minus one. Binary Broadcast Address: 00001010.00000101.01111111.11111111 Decimal Broadcast Address: 10.5.127.255 Assignable IP Addresses: These are all IP addresses within the subnet range, excluding the network and broadcast addresses. First Assignable IP: Network Address + 1 = 10.5.112.1 Last Assignable IP: Broadcast Address - 1 = 10.5.127.254 4
