I get that you’re not doing much with the V6 yet but when passing it through I’m running my own DNS and want not just DNS v4 requests going to my server but also v6 especially for all the little android devices running around swapping themselves over to v6 to get around my filtering on v4, I’ve found they do respect v6 when pushed via DHCP, but that requires a router that won’t let my ISP have all the control.
So, allow DNS override for IPV6 please. Of course, implementing v6 would be even better but I’ll ask small.
