    Your computer is using your switch, but your VM's are using the virtual switches. They are Hyper-V devices and can generally be ignored as long as things are working right. the 172.16.0.0/12 addresses are private IP addressing space used by your VM system for various purposes and is used by default because although 172.16.0.0/12 is private IP space, but few device use that be default and typically use something in the 192.168.0.0/16 or 10.0.0.0/8 IP address ranges.

    Beginning with Windows 10 v1709 and later releases a new switch named Default Switch is created whenever the Hyper-V role is installed, aimed to provide an easy networking solution for virtual machines, the Default Switch allows virtual machines to share the host’s network connection using NAT similar to the way of Internet Connection Sharing (ICS).

  • The Hyper-V Default Switch will randomly use one these IP address ranges based on the host system IP address: Start IP: 192.168.0.0 – End IP: 192.168.255.255 Start IP: 172.17.0.0 – End IP: 172.31.255.255
