Fritzbox - Telekom.de - IPv6 - WIndows vs Mac - Going Crazy

Help

Hi

My debug token is: b7c4yhm6ew

I am going crazy.

I am running pihole (192.168.2.100) on my network.
I installed it today on a Raspi Zero W.
Router is a Fritzbox 7490 (192.168.178.1), newest Firmware.
Macs, iPhone and android phones use pihole, can access http://pi.hole/admin, get advertising blocked, all good.

The windows 10 machines seem to ignore the pihole although they are listed in their DNS settings.

I tried ipconfig /flushdns on the windows clients.

Why does windows ignore the pihole and all other devices use it ?!?

You have another DNS server that is not the Pi-hole set (the IPv6 address)

You mean this one?

How can I get rid of it?
This seems to be the Fritzbox.

Check for a setting in the router. If there is no setting, you can either manually set the address in Windows, or disable DHCP on the router and enable DHCP in Pi-hole.

Got it.

I logged via ssh into the Raspi Zero and did ifconfig.

I notedthe IPv6 address that began with fd00.
I added that IPv6 address of the raspi zero to the Fritzbox config under DNSv6Server in Home Network.

I currently have ULA (Unique Local Addresses ) activated.

Let's see how it goes.

Thanks for your help, Mcat12. Without you I would not have solved it.
