I'm getting that as well on new installs (looking up a host that doesn't exist returns NOANSWER instead of NXDOMAIN)
I think it is related to the change in Net::DNS 0.71 in the changelog:
Fix rt.cpan.org #81787
NXDOMAIN no longer reported by $resolver->errorstring.
Checking $packet->header->rcode as well as $res->errorstring does the trick for me but there may be other repercussions:
