     1  Returns information about one or more networks. By default, this command renders all results in a JSON object. For example, if you connect two containers to the default `bridge` network:
     2  
     3  ```bash
     4  $ sudo docker run -itd --name=container1 busybox
     5  f2870c98fd504370fb86e59f32cd0753b1ac9b69b7d80566ffc7192a82b3ed27
     6  
     7  $ sudo docker run -itd --name=container2 busybox

     9  ```
    10  
    11  The `network inspect` command shows the containers, by id, in its
    12  results. You can specify an alternate format to execute a given
    13  template for each result. Go's
    14  [text/template](http://golang.org/pkg/text/template/) package
    15  describes all the details of the format.

    91  `docker network inspect --verbose` for swarm mode overlay networks shows service-specific
    92  details such as the service's VIP and port mappings. It also shows IPs of service tasks,
    93  and the IPs of the nodes where the tasks are running.
    94  
    95  Following is an example output for an overlay network `ov1` that has one service `s1`
    96  attached to. service `s1` in this case has three replicas.
