Networking with TCP/IP: OSI Model, IPv4/IPv6, and Addressing Design

This report provides a comprehensive overview of TCP/IP networking concepts, focusing on the OSI reference model and its seven layers. It details the functions of each layer, from the physical layer to the application layer. The report includes practical exercises, such as determining subnet masks using a subnet calculator and examining IPv6 packets captured using Wireshark. It further explores the roles of MAC addresses, IP addresses, and the ARP protocol in data communications. A case study is presented, involving detailed addressing design and subnet breakdown for various departments within an organization, along with considerations for upgrading from IPv4 to IPv6. The report concludes with a summary of the key findings and suggestions for future network improvements.
