Your should rather say - it's always bind (bugs). I wrote about bind eating their query counter on IPv6 even if you don't have IPv6 routing:

Run bind with -4 arg or switch to unbound. Bind quality is the same it always has been. Nothing changed after those 25+ years.

Thank you for the article. I tried to report this to the upstream, but it was closed as "not a bug" https://gitlab.isc.org/isc-projects/bind9/-/issues/5898#

Unfortunately bind is as buggy as it always been. I've tried to black hole entire ::/0 but it still eat its query counter without even sending out a single packet.

You need dual stack network and routing to both, or run it with -4 argument for IPv4 only network

And they closing any bug reports is typical "works for me". It's been like this for a long time.
