A /27 (255.255.255.224) is 3 bits on and 5 bits off. This provides 8 subnets, each with 30 hosts. Does it matter if this mask is used with a Class A, B, or C network address? Not at all. The number of host bits would never change.

Maximum Number of IP Addresses:
The maximum number of IP addresses that can be assigned to hosts on a local subnet can be determined by analyzing the subnet mask. In this case, the subnet mask is 255.255.255.224.
Understanding the Subnet Mask:
The subnet mask is used to divide an IP address into a network portion and a host portion. It consists of 32 bits, with the network portion represented by the consecutive 1s and the host portion represented by the consecutive 0s.
Analyzing the Subnet Mask:
The subnet mask 255.255.255.224 can be represented in binary as 11111111.11111111.11111111.11100000.
Counting the Host Bits:
To determine the number of hosts that can be assigned on the subnet, we count the number of consecutive 0s in the subnet mask. In this case, there are 5 consecutive 0s, which means there are 5 bits available for hosts.
Calculating the Number of Hosts:
To calculate the number of possible hosts, we raise 2 to the power of the number of available bits. In this case, 2^5 = 32. However, we need to subtract 2 from this number because the first and last addresses in the subnet are reserved (network address and broadcast address).
Final Answer:
Therefore, the maximum number of IP addresses that can be assigned to hosts on a local subnet with the subnet mask 255.255.255.224 is 30 (32-2). Hence, the correct answer is option 'D'.
