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

Options:

Correct Answer: 62

Solution:

A /26 subnet mask allows for 64 total addresses, of which 62 can be assigned to hosts (2 addresses are reserved for network and broadcast).

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

Step 1: Understand what a /26 subnet mask means. The '/26' 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 addresses in a /26 subnet. Since there are 32 bits in total for an IP address, a /26 subnet leaves 6 bits for host addresses (32 - 26 = 6).
Step 3: Use the formula 2^n to find the total number of addresses, where n is the number of bits for hosts. Here, n = 6, so 2^6 = 64 total addresses.
Step 4: Understand that in every subnet, 2 addresses are reserved: one for the network address and one for the broadcast address.
Step 5: Subtract the 2 reserved addresses from the total addresses to find the number of usable host addresses. So, 64 total addresses - 2 reserved addresses = 62 usable host addresses.
