Yep - thankfully, we have an option.<br>
<br>
Operating two address assignment protocols is just silly.<br>
<br>
At my house, I don't even bother with DHCPv6 for DNS. I just use the<br>
IPv4 ones and let SLAAC assign IPv6 addresses to my devices. Just about<br>
done with the purist madness around this.<br>
