Different type of virtual network in Hyper-V

Currently in Hyper-V Manager, you can create three different type of virtual network, which is External, Internal, and Private. A lot of people may wondering these virtual network behavior and what is the scenario to use them. Below is the brief explanation for each type of virtual network:

If assign External virtual network to virtual machine, the virtual machine is allow to communicate between:

• Virtual machine to virtual machine (two way communication) on the same host
• Virtual machine to parent partition (two way communication)
• Virtual machine to other physical servers (two way communication)

If assign Internal virtual network to virtual machine, the virtual machine is allow to communicate between:

• Virtual machine to virtual machine (two way communication) on the same host
• Virtual machine to parent partition (two way communication)

If assign Private virtual network to virtual machine, the virtual machine is allow to communicate between:

• Virtual machine to virtual machine (two way communication) on the same host

Hope the above information is able to clear your doubt on basic virtual network concept in Hyper-V.
