A subnetted Class B network has the following broadcast address: 144.16.95.255. Its subnet mask
- A.
is necessarily 255.255.224.0
- B.
is necessarily 255.255.240.0
- C.
is necessarily 255.255.248.0
- D.
could be any one of 255.255.224.0, 255.255.240.0, 255.255.248.0
Attempted by 65 students.
Show answer & explanation
Correct answer: D
A broadcast address is calculated by setting all host bits to 1 within the subnet.
For the IP 144.16.95.255, masks like /19, /20, and /21 all result in this broadcast address for different subnets.
Since the specific subnet ID is unknown, the exact mask cannot be uniquely determined from the broadcast address alone.
