🧭 Ever run ifconfig on a modern Linux box and get "command not found"? That is iproute2 doing its job.
The ip command replaced ifconfig, route and arp, and it is also one of the quickest ways to read network state during troubleshooting or incident response.
What the guide covers:
🐧 ip -br addr and ip route for a clean view of interfaces and routes
🔍 ip route get 8.8.8.8 to see the path the kernel would actually use
🛡️ ip neigh to review the ARP/NDP table (an odd gateway MAC is a lead to verify, not proof)
🧰 JSON output with ip -j for scripts and automation, plus VLANs, bridges and namespaces
