Domain 1.0 Networking Concepts
A workstation has IP 192.168.10.45 with subnet mask 255.255.255.224. What is the broadcast address for that subnet?
A192.168.10.31
B192.168.10.63Answer
C192.168.10.95
D192.168.10.255
Why
Mask 255.255.255.224 is /27, meaning 32 addresses per subnet. The host 192.168.10.45 falls into the subnet 192.168.10.32 to 192.168.10.63. The broadcast is the last address in the range, 192.168.10.63.
