The servers don’t respond to queries for names that don’t exist. The
servers (or the firewall in front of them) are misconfigured. All it
does it make it harder to determine if a server is working or not.

Hi Jason.
I just tried this on my server (9.18.11) and it does indeed appear to be
qname minimisation. The following servers (NS for tn.gov) just don't
respond to the query "_.edison.tn.gov":
dns4.tn.gov: type A, class IN, addr 170.141.167.222
dns5.tn.gov: type A, class IN, addr 170.141.168.22

Hi,
Recursive queries to a pair of matching bind 9.16 servers on openbsd 7.0 are
timing out unexpectedly for only two names: "www.edison.tn.gov" and
"www.tn.gov". Both bind instances are otherwise working fine, and have been for
some time.
The query returns a CNAME, and there's a delegation to
5 matches
