Show answer & explanation
Correct answer: D
To find the network address, calculate the block size using 256 minus the subnet mask's last octet: 256 - 240 = 16. Identify the multiple of 16 that is less than or equal to the IP's last octet (213), which is 208. Therefore, the network address is 172.16.123.208.
