Virtualbox Networking Modes

With Virtualbox you get different types of networking modes that can be useful for many purposes. This post is for quick reference for the different virtualbox networking modes.

  • Not Attached - Unplugged.
  • NAT - You get a new IP, like connecting a computer, and you can browse inside. NAT stands for Network Address Translation, which means that you will get a private IP inside the virtualbox (like a computer inside your home, office) and you are accessing the internet from host system.
  • Bridged networking - The virtual machine attaches to your physical network card and exchanges packets directly, circumventing the host operating systems network stack.
  • Internal Networking - Kind of software-based network which is visible to selected virtual machines. Not to applications running on the host or to the outside world.
  • Host-only networking - Network containing host and the set of virtual machines, without the need for the hosts physical network interface. Instead a virtual network (similar to loopback interface) is created on the host, providing connectivity among virtual machines and the host.
