Start with a simple network
Draw your home network: the router, your computer and the devices connected to it. Give each connection a label. This is a useful starting point for understanding how information travels.
Understand addresses and protocols
Learn what an IP address, subnet and default gateway do. Compare DNS with HTTP: one helps find a destination and the other carries a web request. Follow a request from browser to server.
Practice safely
Use your own devices or an isolated practice lab. Try basic connectivity checks and record what changes when a device disconnects. Only inspect traffic on systems you own or have permission to test.
