Given a block of addresses with a /28 subnet mask, calculate the number of useful host IDs available on this subnet and explain how you arrived at your answer.
What will be an ideal response?
Given a subnet mask of /28, there are just 14 available host IDs for this subnet. The formula I used is 2x- 2, where x represents the number of zeroes in the subnet mask. In this case there are four zeroes in the subnet mask, so the calculation would look like this: 24- 2 = 14.
