Hi Alex!

I personally use most often ldns-testns tool to write some tests for 
various dns software, because mentioned tools have usually alternatives 
in utilities provided by bind9. ldns-compare-zones would be more 
interesting to me as well.

Maybe it is unusual to most people, but we write some dns software test 
at lest partially in shell. ldns utilities are very useful for it, but 
not those already implemented.

My blocker for packaging these nice tools in Fedora (and EPEL) is domain 
crate required for them is not released with own release version, not 
even release candidate tag.

Thank you for the ongoing work in any case!

Cheers,
Petr

We'll continue to make occasional use of ldns in an experimental setting, such as during an IETF Hackathon to build a proof of concept for an Internet Draft. However, ldns has been in maintenance mode since 2020, with no plans for major features.
