Network Interfaces & IP
Understand how network interfaces are identified and configured, along with the basics of IP addresses and MAC addresses.
Your Device's Network Doorway
A network interface is your machine's doorway to a network — physical (Ethernet/Wi-Fi card) or virtual. Linux names them eth0, wlan0, enpXsX.
Finding Your Interfaces
The ip a command (short for ip addr show) lists every interface and its details — your primary window into Linux network settings.
