The IPv6 address that begins with "fe80::" is a link-local address, which is used for communication within the local network segment.
Please verify that you have an IPv6 private address associated with the Network Interface. You should see this when viewing the IP configurations of the NIC. If not, you can add the IPv6 here.
If you have IPv6 private address associated with the NIC and are still not seeing it on the VM you will need to update the OS configuration. This page walks you through enabling DHCPv6 for your VM.
