Docker - Networking - List networks

To view existing container networks on the current Docker host:

docker network ls

returns:

NETWORK ID     NAME      DRIVER    SCOPE
45df8a26c099   bridge    bridge    local
99d0975ea463   host      host      local
0190ffd8ff93   none      null      local

NOTE:

Each network gets a unique ID and NAME.
Each network is also associated with a single driver.
- Notice that the “bridge” network and the “host” network have the same name as their respective drivers.

New networks that are created will also show up in the output of the docker network ls command.
