Is there any reliability concerns with your pihole? I feel like the simplest solution would be to turn off DHCP and DHCPv6 on your Fritz, and have the pihole handle all DHCP and DHCPv6 requests. You can leave your Fritz as the same IP, assign static IPs onto your pihole and then let it handle DHCP going forward. It's certainly on my to-do list to move DHCP off my Mikrotik onto a pihole once I get one back up and running again, and comes with the advantage that if you wish you can configure DNS over HTTPS or DNS over TLS on the pihole, to encrypt your DNS requests going out to the wider world.





Anything I say is the ramblings of an ill informed, opinionated so-and-so, and not representative of any of my past, present or future employers, and is also probably best disregarded.

nzkc: I'm not using my Fritz 7390 anymore, however, it sounds like you've got it to where I had it. Although I didn't manually change any IPv6 addresses anywhere. Including the pihole. Can't see it being an issue though.

Happy to dig out the fritz and grab some screenshots if you need them.

 

I didn't change addresses, so much as tell it to use local IPv6 addresses. I think I'm ok without screenshots for now, but thanks for the offer.

The pihole has been working reliably for months on the old R.Pi1, so I'm fairly happy with the reliability. It'll fail at some point, but I have other Pi's around and I can use ISP DNS while it's not working.

 

Using pihole as DCHP is probably simpler and more elegant. However, if it fails it would be more trouble for most to assign a static IP to a computer to log in to return DHCP to the Fritz. I'm on a static IP using a reservation in the Fritz. If I have any problems with my current setup I'll try that, but for now I think I might leave it alone since it seems to be working ok :)

One of the benefits to using the Pi as your DNS servers is that you will see hostnames in the admin web interface / logs instead of IP addresses.

Think you mean DHCP. yes I can see that could be an advantage for some people, I don't really look at the logs.

What most people seem to miss is your IPv6 address is very likely to change if the prefix is issued by your ISP.   But it turns out that doesn't matter in the least.  So long as Pihole is not configured to issue IPv6 addresses, the only thing the IPv6 address is used for is to verify you have IPv6 enabled.   You can actually use ANY public facing IPv6 address in the pihole configuration.  Then in your router you configure the local IPv6 address. e.g. This is mine 

 

fe80::b0fd:1813:5843:b9a23

 

You can configure your network settings so this won't change, ever.

It will be more handy with v5, as you can set block-lists per client for those more chatty devices.
