IPv6 DNS (though DHCP) for Windows devices
Posted: Fri May 26, 2023 9:45 pm
Good afternoon
I have IPv6 running since a couple of months using RA + SLAAC. It works great except Windows devices do not get the DNS server from the RA. It's a know "bug"?. Till now I just set the DNS manually on my Windows 11 devices.
Today, I wanted to look a bit more into it and the workaround seems to enable the IPv6 DHCP to announce the DNS servers to the windows machines.... I followed the few guides I found but I have no idea what I am doing wrong. My Windows 11 machine is not getting any DNS from it.
In the RA/ (ND in Mikrotik) I have enabled the "other configuration" check box. The DHCP client is set on the right interface and I added option 23 with with DNS IPv6. I also tried a few other options numbers but I don't remember which ones. Everyone seems to be saying its 23.
