Properly disable IPv6 for Hyperv

Question

When connecting to vagrant, I get an IPv6 address.

    default: IP: fe80::215:5dff:fe38:151
==> default: Waiting for machine to boot. This may take a few minutes...
    default: SSH address: fe80::215:5dff:fe38:151:22

After reading a lot of articles saying that you should disable IPv6, I tried to do so.

I tried using the script that Microsoft provides. ( https://support.microsoft.com/en-us/help/929852/how-to-disable-ipv6-or-its-components-in-windows )

Which didn't result in getting an IPv4 address also I tried disabling it via the registry. ( http://tweaks.com/windows/40099/how-to-properly-disable-ipv6/ )

I got an IPv4 address once but after reboot I got an IPv6 address again.

Any idea's on how to solve this?

Solution

You can edit each network adapter and uncheck the IP6 binding; in your case edit the Hyper-V Virtual adapter. You may need to reboot for it to take effect. You should no longer have an IP6 address assigned to the adapter. Note you technically have a build Micorosft can say they will not support, but if that is the case, you can re-enable it for the support call. Good luck!

Please be aware that Microsoft explicitly does not support systems with IPv6 disabled. If you need a supported configuration you might want/need to solve this on the vagrant side.

IPv4 and IPv6 addresses are not mutually exclusive and are designed to coexist in peace. Disabling IPv6 does not mean that you will get an IPv4 address instead. If your problem is that your IPv4 address is missing, you should try to find the cause for this, but disabling IPv6 doesn't help at all.

This looks like a bug in Vagrant, not a misconfiguration. You should have a chat with the Vagrant developers about the proper use of IPv6 address scopes, which they haven't done.
