Read on TwitterWhen you start Docker, a default bridge network is created automatically.
You can check this with "docker network ls".
The new containers connect to the default bridge unless otherwise specified.
You can create
Differences:
CUSTOM BRIDGE NETWORK => automatic DNS resolution between containers.

Containers without a --network specified are attached to the default bridge network, so other stacks/services/containers can communicate

To remove a container, you need to stop it and recreate it with different network options.
