Question: What is the maximum number of hosts that can be addressed in a subnet with a /26 prefix?

Options:

Correct Answer: 62

Solution:

A /26 subnet provides 64 IP addresses, but 2 are reserved (network and broadcast), leaving 62 usable host addresses.

What is the maximum number of hosts that can be addressed in a subnet with a /26 prefix?

Step 1: Understand what a /26 prefix means. A /26 prefix indicates that the first 26 bits of the IP address are used for the network part, and the remaining bits are used for host addresses.
Step 2: Calculate the total number of IP addresses in a /26 subnet. The formula to calculate the total number of addresses is 2^(32 - prefix length). For /26, this is 2^(32 - 26) = 2^6 = 64.
Step 3: Identify the reserved addresses. In every subnet, 1 address is reserved for the network address and 1 address is reserved for the broadcast address.
Step 4: Subtract the reserved addresses from the total addresses. So, 64 total addresses - 2 reserved addresses = 62 usable host addresses.
Step 5: Conclude that the maximum number of hosts that can be addressed in a /26 subnet is 62.
