Question:

Using your IP address and your mask, what is your network address? This is determined by converting the IP address and the mask to binary and then proceeding with a bitwise logical AND operation. For example, given the address 172.16.45.0 and the mask 255.255.224.0, we would discover that the network address would be 172.16.32.0.
