IP Addressing Troubleshooting

Use ping and traceroute to test network connectivity and identify failure points.

Verify IP configuration on a Cisco device using `show ip interface brief` and related commands.

Diagnose common IP addressing errors such as incorrect subnet masks, duplicate IP addresses, and misconfigured default gateways.

Apply a systematic troubleshooting methodology (e.g., top-down, bottom-up) to resolve a simulated IP connectivity problem.
