ITECH1102 Networking and Security: Network Planning and Addressing

This assignment solution for ITECH1102 Networking and Security focuses on network planning, specifically addressing IP addressing and routing for an Australian government network scenario. The solution details subnet configurations for various states (NSW, VIC, QLD, WA, SA, TAS, and NT), including allocated IP addresses, subnet masks, and address ranges. It provides routing table entries for edge routers (R1, R2, R3) to facilitate inter-state network communication, specifying destination networks, interfaces, and next hops. Furthermore, the assignment outlines the IP address configuration for Network Interface Cards (NICs) connected to routers in different states, ensuring proper network connectivity. The document includes necessary calculations and configurations to meet the assignment requirements, offering a practical approach to understanding and implementing network infrastructure.
