Q1) Using the IP address 165.1.0.0/16, subdivide the network into at least five subnets. You 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 format? How many hosts will each subnet support? [6Pts]

Q2) Now take the network ID and subnet mask you defined earlier to produce at least five subnets. Using the method just described, define the subnet, host address range, and broadcast address of each subnet and record it in the following table: [8Pts]

Subnet ID

First Host Address

Last Host Address

Broad Cast Address

Q3) 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. [6Pts]
