Answer:
The number of IP addresses available for assignment to network hosts in a network with a network address of 137.65.0.0 and a subnet mask of 255.255.0.0 is 65,534.
Step-by-step explanation:
The subnet mask has 16 bits set to 1, meaning that the number of available IP addresses is equal to 2^(32-16) = 2^16 = 65,536. However, two of these IP addresses are reserved for network and broadcast addresses and cannot be assigned to network hosts, thus the actual number of available IP addresses for network hosts is 65,536 - 2 = 65,534.
