From the above we can see that our vm has 2 network interfaces but only one is configured. The first interface is using NAT and has been assigned an IP address. We will need to add the second interface which is using the host-only network.
We are going to set this second interface (host-only) to a specific IP address: (192.168.56.100)
We might as well change the first interface to a static one too.
> sudo vi /etc/network/interfaces

From the VM, confirm that you can resolve DNS by issueing issuing the following command:
> nslookup google.com
We can also setup port forwarding via our NAT network to access our VM using
> ssh -p PORT test@localhost
