### Using `verbose` option for `network inspect`
`docker network inspect --verbose` for swarm mode overlay networks shows service-specific
details such as the service's VIP and port mappings. It also shows IPs of service tasks,
and the IPs of the nodes where the tasks are running.
Following is an example output for a overlay network `ov1` that has one service `s1`
attached to. service `s1` in this case has three replicas.
```bash
$ docker network inspect --verbose ov1
