Right. If you create a reverse zone in the simplest possible way with tinydns, namely ./add-ns 3.2.1.in-addr.arpa 1.2.3.144, you get 3.2.1.in-addr.arpa. NS a.ns.3.2.1.in-addr.arpa. a.ns.3.2.1.in-addr.arpa. A 1.2.3.144 so that glue is always provided. Unfortunately, neither ARIN nor RIPE supports glue, despite the last paragraph of RFC 1034 section 4.2.2, so reverse lookups on the Internet are unnecessarily rickety. ---Dan
