VLSM Addressing

Using the network diagram and information given create an addressing scheme which utilizes variable-length subnet masks. Show the subnet address and subnet mask in the boxes below (you may need to create text-boxes), color or shade the sub-subnets used in the box (show color code). This company will be using the class C address 220.20.103.0 Remember to start with your largest groups first.
