Hyper-V machines not connecting to the Internet

When you install Hyper-V and you notice that machines are not connecting to the internet, you might need to do some troubleshooting.

In some cases admins may encounter an issue with the Hyper-V machines that don’t connect to internet. There could be various reasons why the Hyper-V machine may not connect to internet. In such cases when there is Internet connection interrupted, the VM will get an APIPA IP address.

A Windows-based computer that gets the IP address from DHCP can automatically assign itself an IP address if a DHCP server is not available. This could occur when probably the DHCP server is temporarily down for maintenance.

The Internet Assigned Numbers Authority (IANA) has reserved 169.254.0.0169.254.255.255 for Automatic Private IP Addressing.

When you use a shared Internet connection between workstation and the Hyper-V Virtual machines, usually we use NAT connection.

NAT gives a virtual machine access to network resources using the host computer’s IP address and a port through an internal Hyper-V Virtual Switch.
