Final answer:
The number of hosts per subnet in 200.100.32.0 255.255.255.224 is 30.
Step-by-step explanation:
To determine the number of hosts per subnet, we need to calculate the number of available IP addresses within the given network range and subnet mask. In this case, the network range is 200.100.32.0 and the subnet mask is 255.255.255.224. The subnet mask represents the number of network bits and the remaining bits represent the host bits.
By counting the number of zeros in the subnet mask, we can determine the number of host bits. In this case, the subnet mask has 27 consecutive zeros, which means there are 2^5 (32) possible combinations of host bits. However, the first and last combinations are reserved for the network and broadcast addresses, so the number of usable hosts per subnet is 32 - 2 = 30.
