You are required to differentiate and analyse its IP enterprise network as shown. The public Internet Protocol (IP) address range is provided by the chief engineer (refer to Appendix A). You are to design an efficient IP addressing scheme for the company. You need to show IP Address calculation working to proof your own work. Use the space provided below to indicate your workings (including the unused IP address range) and then fill up Table 1 and Table 2 accordingly. IP Address Calculation Working. Show your working clearly.
