You can see information about the network using docker network inspect.\n\nWhen no containers are connected to the overlay network, its configuration is not very exciting\n\nBounded code example (external data; do not execute automatically):\n```console\n$ docker network inspect my-network\n[\n    {\n        \"Name\": \"my-network\",\n        \"Id\": \"fsf1dmx3i9q75an49z36jycxd\",\n        \"Created\": \"0001-01-01T00:00:00Z\",\n        \"Scope\": \"swarm\",\n        \"Driver\": \"overlay\",\n        \"EnableIPv6\": false,\n        \"IPAM\": {\n            \"Driver\": \"default\",\n            \"Options\": null,\n            \"Config\": []\n        },\n        \"Internal\": false,\n        \"Attachable\": false,\n        \"Ingress\": false,\n        \"Containers\": null,\n        \"Options\": {\n            \"com.docker.network.driver.overlay.vxlanid_list\": \"4097\"\n        },\n        \"Labels\": null\n    }\n]\n```\n\nIn the above output, notice that the driver is overlay and that the scope is swarm, rather than local, host, or global scopes you might see in other types of Docker networks. This scope indicates that only hosts which are participating in the swarm can access this network.\n\nThe network's subnet and gateway are dynamically configured when a service connects to the network for the first time. The following example shows the same network as above, but with three containers of a redis service connected to it. …\n\nAttribution: Adapted from Docker Documentation under Apache-2.0.
