I wanted to create a test networking lab Ubuntu on 16.04 for trying out configurations without having to hack my real LAN about. I decided to use VirtualBox virtual machines as they are freely available and work with Linux and you can also use MS Windows guests. The network in the test networking lab Ubuntu on 16.04 will need to separate from our own normal LAN. VirtualBox provides this out of the box. We simply set the network interfaces to us “Internal Network”. This way only VM’s on the host can see each other.
I’m always playing around with new IT technology. Up until recently I just did it with VirtualBox on my PC’s and messed with the network and then cleared up the mess afterwards. This was not good, not to mention a waste of time when I could be playing around with the next new shiny bit of tech or software.
