Internal, External and Private Network in Hyper-V

Internal, External and Private Network in Hyper-V are the three different kinds of network which we are using to interconnect the different VM’s with internal as well as the external network. Internal, External and Private Network in Hyper-V are the most important network configurations which we need to be clear. If you are going to plan a enterprise network for with Windows Server 2012 R2 and Hyper-V Server, you need to know the three differences between these Hyper-V Network configurations. According to the needs

  • you need to install the Physical Network Cards,
  • you need to configure the physical network adapters,
  • you need to create the virtual switch,
  • you need to create the virtual network adapters,
  • you may also need to configure the physical switch and the routers.

below are the detailed explanation about the Internal, External and Private Network in Hyper-V

Virtual Switch : External Network

The virtual switch is bound to the networking protocol stack in the host OS and connected to a physical network interface adapter in the Hyper-V server. VMs running on the server’s parent and child partitions can all access the physical network to which the physical adapter is connected.

Virtual Switch : Internal Network

An internal network switch is bound to a separate instance of the networking protocol stack in the host OS, independent from the physical network interface adapter and its connected network. VMs running on the server’s parent and child partitions can all access the virtual network implemented by the virtual switch, and the host OS on the parent partition can access the physical network through the physical network interface adapter, but the VMs on the child partitions cannot access the physical network through the physical adapter.

Virtual Switch : Private Network

A private network switch exists only in the Hyper-V server and is accessible only to the VMs running on the child partitions. The host OS on the parent partition can access the physical network through the physical network interface adapter, but it cannot access the virtual network created by the virtual switch.

These virtual switches needs to be created while you are configuring the virtual network in the Hyper-V.
