🌐 Network Project Toolkit is the complete English-language guide to a modern networking toolkit for engineers, students, and homelab builders. Learn how to scan networks, capture traffic, analyze packets, simulate topologies, and document infrastructure — all with free and open-source tools. Built for CCNA candidates, sysadmins, and anyone building or debugging a network. Completely free. No signup. No paywall. No hidden chapters.
Most networking tutorials throw a list of tools at you. This toolkit shows you a real project workflow — discover hosts, capture traffic, analyze protocols, simulate a topology, and document the result. Every step is a runnable exercise.
