What command is used to list all Docker networks?

The command used to list all Docker networks is "docker network ls." This command provides a straightforward way to view all the networks that are currently created in your Docker environment. When executed, it displays a list that includes the network names, IDs, drivers used, and other pertinent details that help users identify and manage the different networking configurations present in their Docker setup.

Using this command is essential for administrators who need to manage Docker containers and understand how they are interconnected through various networks. It also aids in troubleshooting network issues by allowing users to confirm which networks are available or need to be created.

Other commands listed serve different purposes. For instance, "docker network show" isn't a valid command, while "docker network list" is often regarded as an informal reference to the "ls" command but does not exist in Docker's CLI. "docker network inspect" is used to inspect detailed information about a specific network rather than listing all available networks. Therefore, "docker network ls" is the appropriate and correct choice for listing all Docker networks.
