A. B. C. D.A
To determine the network address, you need to perform a bitwise AND operation between the IP address and the subnet mask.
Let's convert the IP address and subnet mask to binary:
IP address: 10101100.00010000.00011100.11111100 Subnet mask: 11111111.11111111.11110000.00000000
Performing a bitwise AND operation between the IP address and the subnet mask gives you the network address:
Network address: 10101100.00010000.00010000.00000000
Converting this binary network address back to decimal notation, we get:
172.16.16.0
Therefore, the correct answer is A. 172.16.16.0.
