I'm interested in the same subject.
What is the usual way of checking if DNSSEC stuff is in order at the
Name Service provider?
What we do we call these functions in the following sequence:
and in case of error in denial of existence RR (incorrect "from" -
"to" range), we will hit the error in ldns_verify() with e. g.
LDNS_STATUS_DNSSEC_NSEC_RR_NOT_COVERED. This does not show us that the
error is denial of existence RR.
Maybe there's a known way of doing these checks properly?
