Pihole has a few drawbacks when your systen grows - a lot of things then need to be done by hand that others do either automated or at least easier.

Personally I have become very fond of technitium - it does everything you will ever need and the main drawback is that it seems so fucking overwhelming initially. But: Once you figured out that you basically only need 10% of the fields it becomes easier. And it’s fucking solid and just works and works and works.

Not a fan of Pi-hole itself, but other than that,why not?

(Technitium DNS has some advantages down the road)

That is a bad setup then. Not an issue of the software or hardware.
