Be sure that your subnetworks do not overlap. If they do, the network create fails and Engine returns an error.
When creating a custom network, the default network driver (i.e. `bridge`) has additional options that can be passed.
The following are those options and the equivalent docker daemon flags used for docker0 bridge:
| Option | Equivalent | Description |
|--------------------------------------------------|-------------|-------------------------------------------------------|
| `com.docker.network.bridge.name` | - | bridge name to be used when creating the Linux bridge |
| `com.docker.network.bridge.enable_ip_masquerade` | `--ip-masq` | Enable IP masquerading |
| `com.docker.network.bridge.enable_icc` | `--icc` | Enable or Disable Inter Container Connectivity |
| `com.docker.network.bridge.host_binding_ipv4` | `--ip` | Default IP when binding container ports |
| `com.docker.network.mtu` | `--mtu` | Set the containers network MTU |
| `com.docker.network.enable_ipv6` | `--ipv6` | Enable IPv6 networking |
For example, now let's use `-o` or `--opt` options to specify an IP address binding when publishing ports:
```bash
$ docker network create -o "com.docker.network.bridge.host_binding_ipv4"="172.23.0.1" my-network
