1. Using the same address of 165.1.0.0/16, subdivide the network into at least five subnets. how doi need to configure the subnet mask to create an extension of the network ID, allowing for additional subnets. How many bits of the host portion of the subnet mask do you need to "borrow"? What will the resultant subnet mask be in decimal value? How many hosts will each subnet support?

2. Using the techniques practiced in the preceding steps, create a table of the custom subnet masks. Include the appropriate values for both the binary and decimal representations; number of subnets; and the number of Class A, Class B, and Class C hosts for each subnet mask. The first two subnets have been calculated already as examples.

3.Take the original network ID of 192.168.5.0/24 and calculate the custom subnet mask to produce at least five subnets for the lab network.
