A host-only network is a virtual network that acts as a LAN, but its reach is limited to the host that is running the virtual machines without exposing them to external systems. This kind of network also provides a virtual adapter for the host to communicate with the virtual machines as if they were in the same network segment.

With the configuration we just made, we will be able to communicate between the machine that will take the roles of client and attacking machine in our tests and the web server that will host our target applications.
