VirtualBox - shawfdong/hyades GitHub Wiki

VirtualBox networking modes:

• Network Address Translation (NAT) (not to be confused with NAT Network, which is a new NAT flavour introduced in VirtualBox 4.3). Note all guests with NAT have the same IP 10.0.2.15/24, they can't be pinged from the host, or obviously from each other. The guest can reach outside.
• Host-only networking, a network containing the host and a set of virtual machines. virtual network interface (similar to a loopback interface) is created on the host, providing connectivity among virtual machines and the host.In this network, the host can ping the guests and guests can ping each other. But the guests can connect to outside world.
