Refer to the truth table for the possible outcomes ANDed result Step 3 Convert the answer back into decimal The IP address belongs to the network when a mask of is used. Question 2 What is the network number of the IP address if it has a subnet mask of Notice that the IP address is the same as in Question 1 but the subnet mask is different. What answer do you think you will get The same one Let s find out Answer Step 1 Convert both the IP address and the subnet mask to binary Step 2 Perform the AND operation to each pair of bits 1 bit from the address ANDed to the corresponding bit in the subnet mask. Refer to the truth table for the possible outcomes ANDed result Step 3 Convert the answer back into decimal The IP address belongs to the network when a mask of is used. 14 Binary ANDing So Why AND Good question. The best answer is to save you time when working with IP addressing and subnetting. If you are given an IP address and its subnet you can quickly find out what subnetwork the address belongs to. From here you can determine what other addresses belong to the same subnet. Remember that if two addresses are in the same network or subnetwork they are considered to be local to each other and can therefore communicate .
