Problem with ipv6 DNS

[sorinut]

I'm running a pi-hole on my network and I'm trying to get the router to broadcast it's IPv6 address instead of the router.

For IPv4, all the clients receive the correct DNS address of 192.168.1.10, but for IPv6, they all get ::1, which is the routers address. I have put the address of the pihole in the "IPv6 DNS Server 1", but it doesn't make any difference. All IPv6 address assigned to each device continue to be ::1. When I manually change them on the devices, everything works.

Not an expert in this, but the line in /etc/dnsmasq.conf that sets the IPv6 dns server is:

dhcp-option=lan,option6:23,[::]

if you use custom scripting, you can write a dnsmasq.postconf and replace the [::] with the ip of your server.

Never tried to use Pi-hole but doesn't it do the same as Ab-Solution?

Thank You for this info. I will work on this weekend after I do a factory reset of my RT-AC88U
