Hi ABH, The test that failed counted the recursive steps towards a.t.net-dns.org. When asking the .org authoritative about net-dns.org, it received four possible authoritative nameservers, but glue for just one: ns1.net-dns.org. The server listening on ns1.net-dns.org was down (triggering the error) and the other nameservers were not tried because their IP address was unknown. I think this is an error an will look into it. Thanks for the report.

Hi ABH, I'm happy to tell you that this issue is now resolved in trunk. When recursing, the IP addresses of delegation nameservers were looked up only when no glue records were available for none of the delegations at all. With glue, the other (glueless) nameservers were simply dropped. This was obviously wrong. I have fixed it in such a way that the IP's of the other nameservers are looked up if querying the one with glue failed. This at least leads to an answer, but can take many more queries then the minimum needed. t/10-recurse.t had to be fixed to accept at least 3 i.s.o. precisely 3. Because of some other broken nameservers, it took 48 queries for a.t.net-dns.org. (with a non responsive ns1.net-dns.org). Ideally one would wish to lookup the nameserver "to be queried" only (when necessary), but that is out of the scope of this ticket. Thanks again for our report, -- Willem
