| 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. | We want to use a dedicated subnet / network specifically for containers, so they don't trample over the **SERVER** and **LAN** networks.

|  |     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. | ||||||
