ITECH1102 Networking and Security: IP Addressing and Routing Table

This assignment solution focuses on network planning, specifically IP addressing and routing, within the context of the ITECH1102 Networking and Security course. The scenario involves allocating IPv4 addresses to Australian states and building a routing table for edge routers to connect them. The solution provides details on nodes needed and allocated, network addresses, subnet masks, and valid IP ranges for each state. It includes IP addresses and subnet masks for Northern Territory, Tasmania, South Australia, Western Australia, New South Wales, Victoria and Queensland. The assignment also covers the creation of routing tables for edge routers R1, R2 and R3, specifying destination networks, interfaces, and next hops. Finally, the solution provides the IP addresses for the Network Interface Cards (NIC) to connect NT, WA and SA routers.
