-  * Internal network, or the home network, is the network (or networks) that sits on top of your [[:networking|backbone]] and connects all your home devices (home automation, webcams, server, computers, tablets...) together. You can have one single flat home network or a mix of different subnets for different purposes, like one for home automation devices, one for webcams, one for computers.+  * Internal network, or the home network, is the network (or networks) that sits on top of your [[networking:networking|backbone]] and connects all your home devices (home automation, webcams, server, computers, tablets...) together.
