Hi! We soon put ALIAS into production. Hence, I have some questions to better understand what's going on internally in PDNS.
a) What happens if the backend query (from PDNS-auth to resolver) is unanswered? Will PDNS timeout the outstanding query or will it be kept on the list for ever? If it times out - will PDNS send any responses? I stopped the resolver and sent a query to an ALIAS RR. My obervation is, that PDNS did send an upstream query, but it: - does not resend to the resolver - does not send any response (eg SERVFAIL) upstream Hence I supsect that such unanswered backend queries will resist in some queue forever. Can you please comment an what really happens if the resolver is not available? b) AFAIS the backend query supports only UDP without EDNS0. Hence, only resposnes up to 512 bytes. Correct? c) AFAIS queries to ALIAS RRs are not cached in the packet cache. Why not?
