"dig <host> +trace" adds "+dnssec".   "Applications don't necessarily need
DNSSEC support to benefit from it. If the local nameserver is configured to
make DNSSEC mandatory, then the applications will receive a SERVFAIL error
trying to access any domain that is DNSSEC enabled if the signature data
isn't valid."  See: https://wiki.debian.org/DNSSEC
