I'd just turn it on in the Pi-hole first; it would have been easier if it had been been done during the installation, but you can do it following the instructions on this page: Pi-hole on Raspberry Pi with IPv6 - Arif Amirani under "IPv6 on Pi-hole".
Let it try to sink the requests.
You don't have to add the DNS IPV6 address to the pi-hole, it will autoconfigure one unless it gets one from the router (and it shouldn't) . Use that address for IPv6 for devices lookup.
manually in the devices if your router handles DHCP and it is not manually configured to your Pi-hole for DNS lookups.
Really, this is not how I did it; I did it in the installation and point both to the pi-hole from my router.
If that does not work, then I'd try turning it on in the router but I doubt it will matter. If the iOS devices are not showing up at all, they are bypassing the Pi-hole somehow.
Like I said: I have a pi zero w. I do not use it for anything other than DNS.
Yeah, I think DNS on IPv6 on their setup is getting upstream: my gateway is set up to do nothing but passthrough to my router but I know ISPs can change settings on a whim.
edit
and DoH would be exactly what I thought the apps were doing ( but I admit, I did not know what it was called) in my first reply; but how could you check that in an app?
So in IOS 15 there is “private relay” which you would want to turn off. In IOS 14 it’s available only as configuration option for app developers
In addition I would strongly recommend looking into IPtable rules to redirect all DNS requests to Pi-hole, blocking common DNS over TLS ports (usually only port 853) and blocking all known DoH hosts if you really want to get into the weeds.
I sent dosch an email and it does not show up in the thread; I am curious how you saw it?
Anyway:
I do not get ads. Period.
I use 'the Brave Browser' with adblock and the pi-hole. the browser and the extension block so many ads my pi-hole only has to block ~<30% of requests.
Anyway: please ensure your emails are being seen by the community. I'm new here and confused why you saw my reply and it is not in the thread.
I see your reply in email but when I look at the thread I see no more comments beyond "I'd just turn it on in the Pi-hole first; it would have been easier if it had been been done during the installation, but you can do it following the instructions on this page: Pi-hole on Raspberry Pi with IPv6 - Arif Amirani under "IPv6 on Pi-hole"."...
Again, I'm new to the forum and your replies are only showing up, to me, as emails.
dosch was the OPer.
I check the forum, I see I have a reply and it has become a new, email, chain.
I only sent a reply to dosch as an email because the forum said something like "three posts to dosch; get a room". So I did.
Hmm okay it looks like you have mistakenly created a new topic, which was why I was confused to what you were saying. (You are effectively OP for this as far as I can see)
I have also mistakenly replied to you (I thought you were just a little confused and ran with it, thinking you needed help)
Best you close this one which you will need to do by logging in
