--- page_title: "Networking - VirtualBox Provider" sidebar_current: "virtualbox-networking" --- # Networking ## VirtualBox Internal Network The VirtualBox provider supports using the private network as a VirtualBox [internal network](https://www.virtualbox.org/manual/ch06.html#network_internal). By default, private networks are host-only networks, because those are the easiest to work with. However, internal networks can be enabled as well. To specify a private network as an internal network for VirtualBox use the `virtualbox__intnet` option with the network. The `virtualbox__` (double underscore) prefix tells Vagrant that this option is only for the VirtualBox provider. ```ruby Vagrant.configure("2") do |config| config.vm.network "private_network", ip: "192.168.50.4", virtualbox__intnet: true end ``` Additionally, if you want to specify that the VirtualBox provider join a specific internal network, specify the name of the internal network: ```ruby Vagrant.configure("2") do |config| config.vm.network "private_network", ip: "192.168.50.4", virtualbox__intnet: "mynetwork" end ```
