Australian Government Network Planning Assignment: ITECH1102 Solution

This document presents a complete solution for the ITECH1102 Networking and Security Network Planning assignment. The assignment focuses on allocating public IPv4 addresses and constructing routing tables for edge routers to connect Australian states, mirroring a scenario where the student acts as a Network System Administrator. The solution details the IP address allocation for each state, including the network address, slash mask, and valid IP range, along with the subnet mask and the number of available addresses. It also includes routing tables for edge routers (R1, R2, and R3), specifying destination networks, interfaces, and next hops. The assignment demonstrates practical application of subnetting and routing concepts in a real-world network design context, referencing relevant materials such as "Addressing" from Next Generation Optical Network Design and Modelling and the Wikipedia entry on Subnetworks, showcasing how to design and configure a network infrastructure.
