Bridged networking Used in environments where virtual machines provide services or participate in a real  network. Connects virtual machines to the Local Area Network (LAN) of their host machine, whether wired or wireless, and allows them to connect to any other host or virtual machines (if they are also bridged) on the network. Connects the virtual network adapter in a virtual machine to the physical Ethernet adapter in its host machine. You can establish additional virtual bridges to use in custom configurations that require connections to more than one physical Ethernet adapter on the host computer. The default network adapter interface is  vmnet0 . Host-only networking Used in isolated test environments where virtual machines do not need to communicate with other environments. Connects virtual machines to a private LAN shared only by their host machine and any other virtual machines also using host-only networking. Other host machines on ...
