You are troubleshooting an issue and need to see a list of all Compute Engine instances currently running in your project, along with their internal and external IP addresses.

Which gcloud command provides this inventory?

The `gcloud compute instances list` command is the standard way to view your current VM inventory. By default, it returns a tabular output showing the instance name, zone, machine type, internal IP, external IP, and current status (e.g., RUNNING, TERMINATED) for all instances in the active project.
