### Engine
There are two IP ranges used by the engine for the `docker0` and `docker_gwbridge` interface:
#### docker0
By default, the Docker creates and configures the host system with a network interface called `docker0`, which is an ethernet bridge device. If you don’t specify a different network when starting a container, the container is connected to the bridge and all traffic coming from and going to the container flows over the bridge to the Docker engine, which handles routing on behalf of the container.

Docker configures `docker0` with a configurable IP range. Containers which are connected to the default bridge are allocated IP addresses within this range. Certain default settings apply to `docker` unless you specify otherwise. The default subnet for `docker0` is `172.17.0.0/16` and the default maximum transmission unit (`MTU`) is `1500` bytes.

The `docker_gwbridge` is a virtual bridge that connects the overlay networks (including the `ingress` network) to an individual Docker engine's physical network. Docker creates it automatically when you initialize a swarm or join a Docker host to a swarm, but it is not a Docker device. It exists in the kernel of the Docker host. The default subnet for `docker_gwbridge` is `172.18.0.0/16`.
If you need to customize its settings, you must do so before joining the Docker host to the swarm, or after temporarily removing the host from the swarm. The recommended way to configure the `docker_gwbridge` settings is to use the `daemon.json` file. You can specify one or more of the following settings to configure the network:

### Swarm
Swarm uses a default address pool of `10.0.0.0/8` for its overlay networks. If this conflicts with your current network implementation, please use a custom IP address pool. To specify a custom IP address pool, use the `--default-address-pool` command line option during [Swarm initialization](../../../../engine/swarm/swarm-mode.md).
