What is the maximum number of hosts that can be addressed in a /24 subnet?

Step 1: Understand what a /24 subnet means. A /24 subnet means that the first 24 bits of the IP address are used for the network part.
Step 2: Calculate the total number of IP addresses in a /24 subnet. A /24 subnet has 2^(32-24) = 2^8 = 256 total IP addresses.
Step 3: Recognize that in every subnet, 2 IP addresses are reserved. One is for the network address and one is for the broadcast address.
Step 4: Subtract the 2 reserved addresses from the total. So, 256 total addresses - 2 reserved addresses = 254 usable addresses for hosts.
