What is the maximum number of hosts that can be addressed in a /22 subnet?
Step 1: Understand what a /22 subnet means. The '/22' indicates that the first 22 bits of the IP address are used for the network part, and the remaining bits are for host addresses.
Step 2: Calculate the total number of addresses in a /22 subnet. There are 32 bits in total for an IP address. So, we subtract 22 from 32: 32 - 22 = 10.
Step 3: Use the result from Step 2 to find the total number of addresses. We calculate 2 raised to the power of 10: 2^10 = 1024. This means there are 1024 total addresses in a /22 subnet.
Step 4: Understand that in any subnet, 2 addresses are reserved: one for the network address and one for the broadcast address. This means we need to subtract 2 from the total addresses.
Step 5: Subtract 2 from the total addresses calculated in Step 3: 1024 - 2 = 1022. This gives us the maximum number of usable host addresses in a /22 subnet.
