Describe the contents and purpose of a subnet mask.

What will be an ideal response?


The subnet mask identifies which part of an IP address is the network portion and which part is the host portion. A computer or other device can use its subnet mask to know if an IP address of another computer is on its network or another network. A subnet mask has 32 bits and is a string of 1s followed by a string of 0s, for example, 11111111.11111111.11110000.00000000. The 1s in a subnet mask say, "On our network, this part of an IP address is the network part," and the group of 0s says, "On our network, this part of an IP address is the host part.""
