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.

To me a huge benefit of unbound is that it allows to return whatever you want for wildcards.
Including TLD wildcards.
Seychelles DNS has been hijacked as a whole and only serves malware? Null route the entire .sc.
.ru ? Nah, that won't resolve at my place.
etc.
Then unbound is at ease, even on an old Raspberry Pi, with blocklists made of hundreds of thousands of lines.
