We want to use a dedicated subnet / network specifically for containers, so they don't trample over the **SERVER** and **LAN** networks. If you are unsure of the name of the network adapter, in this case `eth0`, just type `ipaddr` in the terminal to list the network interfaces to locate it.
```
docker network create -d macvlan --subnet=192.168.5.0/24 --gateway=192.168.5.1 -o parent=eth0 docker_network
```
```
!!! note
Be sure to replace `eth0` with the correct interface name using `ip addr` in the terminal. e.g. It may appear as something else like `ens18`, etc. If the interface doesn't exist, Docker will produce an error complaining about it.
