Hosts on a local subnet uses the subnet mask 255.255.255.224.Find the maximum number of IP addresses that can be assigned to such hosts?

The subnet mask 255.255.255.224 corresponds to a /27 in CIDR notation. This means that there are 5 bits available for host addresses (32 total bits - 27 bits for the network = 5 bits for hosts).

The formula to calculate the number of available host addresses in a subnet is 2^n - 2, where n is the number of bits available for host addresses. The "-2" accounts for the network address and broadcast address, which cannot be assigned to hosts.

So, in this case, the maximum number of IP addresses that can be assigned to hosts is 2^5 - 2 = 32 - 2 = 30.
