VirtualBox has a bug where the IPv6 route is lost on every other configuration of a host-only network. This is also triggered when a VM is booted. To fix this, we test the route-ability of all IPv6 networks, and reconfigure if necessary. This is very fast but we still only do this if we have any IPv6 networks.
