Ideally, it would be nice to be able to specify the DNS servers in DHCPv6 options as Windows does not support ND RDNSS.
Also with IPv6 ND, I would like to be able to manually configure the DNS servers to advertise. For example as it stands it will not use the RouterOS cache only the servers it caches.
IPv6 ND Bug: I've removed the DNS servers from the IP DNS config but it's still advertising the old IPv6 servers instead of the new one. I've rebooted to no avail also when I export the config there is no mention of them. If I delete the ND config and recreate they're still there.
To get windows and Android over the line you need to be able to issue the DNS server by DHCP options and ND in an IPv6 only environment. https://en.wikipedia.org/wiki/Compariso ... ng_systems
Currently, I'm issuing an IPv4 IP address with the DNS information due to IPv6ND not being able to advertise the router dns server and DHCPv6 not being able to be configured with a DNS server for Windows clients.
