I set up authoritative nameservers at home using unbound, which appears to be considerably easier than configuring BIND, but I still can't say that I fully understand it. DNS (and networking in general) is a bit of a dark art.

Its easy to feed an RBL to unbound to do pi-hole type work, I use pf to transparently redirect all external DNS requests to my local unbound server but I get the bind automation around things like DNSSEC, DHCP ddns and ACME cert renewals.
I'm surprised this isn't a more common stack.
