How would I go about completing this chart?

If you don't mind explaining how to get these values?

Question 1: IP ADDRESS EXERCISES - CLASS A SUBNETTING For the following network 72.XX.X and Subnet mask 255.252.0.0 (114) Complete the following charts writing the full IP address. Show your work, calculations and THE FIRST 5 SUBNETS to get full marks. Block Size # of Subnets # of Hosts per subnet [3] Subnet ID Broadcast Address Valid Host Range [5] Question 2: IP ADDRESS LABELLING - CLASS C SUBNETS . Draw a diagram of a network based on your answer to question 1. You may hand draw the network or use packet tracer or GNS3 but it must have the following features. Include 2 routers connected to one another Each router is connected to 2 switches (for a total of 4 switches in your diagram) Each switch should be connected to 3 PCs (for a total of 12 PCs) [1] Label IP addresses Each broadcast domain must be its own subnet and IP's must be assigned according the chart you completed in question 1. Router MUST have the first valid host Between the two routers use the first and second valid host impossible to give both routers the first host) Switches do not need IP addresses . In total you will be assigning 18 IP addresses . . [5] note: even if your answer to question 1 is incorrect, I will use your chart for this question (you will not lose additional marks for making a mistake in question 1) You do not need to include this page, simply your diagram with the labelled IP addresses Question 3: VARIABLE LENGTH SUBNETTING XYZ Company IP addressing and subnet requirements: Public (registered) IP address = 199.10.20.X /24 (the x means they reserve from 0 to 255) Subnet and Host Requirements Department Hosts Required Block Size Needed? Leftover Hosts Teachers 34 Students 2 IT 30 Admin 1 2 x Support Staff (2 subnets) 2 *13 hosts (2 separate subnets of 13 hosts) 4 WAN network links (4 2 * 4 hosts subnets) (4 separate subnets of 2 hosts) Total: [3] Complete the chart for each subnet (if you do it correctly the chart will be full!) Network Name Block Size Subnet ID (199.10.20.) Broadcast ID (199.10.20.) [5] WAN1 WAN2 WAN3 WAN4
