A network with address 208.40.224.0/24 is divided into /28 subnets. What is the host address range of the fourth subnetwork?

Answer options

• A. 208.40.224.17 "" 208.40.224.30
• B. 208.40.224.33 "" 208.40.224.46

• D. 208.40.224.65 "" 208.40.224.78

Correct answer: C

Explanation

The correct answer is C because the fourth /28 subnet starts at 208.40.224.48 and ends at 208.40.224.61, giving the host address range of 208.40.224.49 to 208.40.224.62. Options A, B, and D represent ranges from other subnets, thus they are incorrect.
