IPv6 with custom DNS server

2024-11-11 10:55:33

Tags: #IPv6

Model: Archer AX1500

Hardware Version: V1

Firmware Version: 1.3.10 Build 20240130 Rel. 77367(4555)

Does anyone have experience with using internal DNS server for IPv6? I've found that when using the default settings (prefix delegation enabled, SLAAC) there are some issues:

When settings a custom DNS server the prefix is changed (and hence the DNS server address is also changed)
When trying to use a private or link-local address it is not accepted by the router

It would be nice to have some way to provide IPv6 clients with a custom DNS server address, while retaining the recommended configuration with the ISP (not configuring static IPv6 address on the device).

Maybe there is some way to do this?

@Sunshine Thanks, this would be great. I'd think that easy fix would be to allow private and link-local addresses (fc/fe) as IPv6 DNS servers. My use case would be to use this to for content filtering and ad blocking.
