Hi. I got a Pi as a holliday gift and decided to try out the Pi-hole. I'm completely new to the topic, but went through all the instalation process and stuck on trying to make my router use my pi as a custom DNS.
Basically, the option is not there and I'm not sure whether it's possible to still use pi-hole (I know I can specify DNS on every single client I use but that's a bit janky).
The fiber router (provided by my ISP) uses IPv6, ISP support says there's no way to specify DNS for IPv6 connection.
There are two kinds of distinct DNS resolver settings:
The upstream DNS resolver your router is using (often, a WAN/Internet kind of option), and the local DNS resolver your router tells its clients to use, which usually defaults to the router itself (often, a LAN/DHCP kind of option).
Not all routers would expose configuration options for both.
From what you've shared, it seems that you are dealing with the router's upstream resolvers so far.
Does your router perhaps allow you to set a local DNS resolver?
If so, that would be the preferred way.
LAN only allows to set up routers IP and netmask.
DHCP is just IPs pool
DHCP hosts contains all connected devices and parental settings for them.
DNS relay is on/off radiobutton (still not sure what does it do, because in both positions my devices use my router as a DNS).
And mesh settings.
Documentation is severely lacking any information except Wifi settings. I will try to go ask on the ISP forum, maybe they'll help.
Thank you!
You could consider to disable your router's DHCP server and enable Pi-hole's.
NOTE that you'd need to configure a static IP on the device that runs your Pi-hole.
Use your Pi-hole host's preferred network management tool to achieve that.
