VLSM questions

In this activity, you have been given the network address 172.16.0.0/16 to subnet and provide the IP addressing for the network shown in the Topology Diagram. VLSM will be used so that the addressing requirements can be met using the 172.16.0.0/16 network. The network has the following addressing requirements:

The R1 LAN 1 will require 8,000 host IP addresses.

The R1 LAN 2 will require 4,000 host IP addresses.

The R2 LAN 1 will require 2,000 host IP addresses.

The R2 LAN 2 will require 1,000 host IP addresses.

The R3 LAN 1 will require 500 host IP addresses.

The R3 LAN 2 will require 200 host IP addresses.

The serial link from R1 to R2 has been preconfigured with the 209.165.202.0/30 network.

The serial link from R1 to R3 has been preconfigured with the 209.165.202.4/30 network.

The serial link from R2 to R3 has been preconfigured with the 209.165.202.8/30 network.

Questions:

1. How many subnets are needed?

2. What is the maximum number of IP addresses that are needed for a single subnet?

3. What is the total number of IP addresses that are needed?

4. What is the total number of IP addresses that are available in the 172.16.0.0/16 network?

Please explain how you get the answer.
