ITECH1102 Networking and Security Network Planning Assignment Solution

This document presents a solution to a network planning assignment for the ITECH1102 Networking and Security course. The assignment involves designing a network for the Australian states, including allocating public IPv4 addresses, subnetting, and configuring routing tables for edge routers. The solution provides detailed IP address assignments for each state (Western Australia, Victoria, Tasmania, South Australia, Queensland, Northern Territory, and New South Wales), along with the corresponding subnet masks and usable ranges. It includes the routing tables for routers R1, R2, and R3, specifying destination networks, interfaces, and next hops. Additionally, the solution details the IP addresses assigned to the Network Interface Cards (NICs) of each router, ensuring proper connectivity between the states. The document references relevant network engineering principles and resources, offering a practical application of network design concepts.
