That's as much as we can determine without DNSSEC. And it breaks if a DNS server returns NXDOMAIN for ENT's. fujiwara-dnsop-nsec-aggressiveuse addresses the case where 'a.example' exists, but the range 'bxxxx.example' thru 'gyyyy.example' do not exist, found by a single query for anything in the range. But it only works with DNSSEC signed zones. -- Bob Harold
