What is the maximum number of hosts that can be addressed in a /30 subnet?
Step 1: Understand what a /30 subnet means. The '/30' indicates that the first 30 bits of the IP address are used for the network part.
Step 2: Calculate the total number of addresses in a /30 subnet. A subnet with a /30 mask has 2^(32-30) = 2^2 = 4 total addresses.
Step 3: Identify the types of addresses in the subnet. In any subnet, one address is reserved for the network and one for the broadcast.
Step 4: Subtract the reserved addresses from the total. Since 2 addresses are reserved (1 for network and 1 for broadcast), you have 4 - 2 = 2 usable addresses for hosts.
Step 5: Conclude that the maximum number of hosts that can be addressed in a /30 subnet is 2.
