Hi,
is there any reason for ns.ripe.net missing NS records of /24 reverse zones out of /16 reverse zones? Anyway we've a problem resolving ip addresses out of a couple of /16 reverse zones when asking ns.ripe.net as one of the secondaries for such a zone.
Any thoughts or hints?
Christian,
ns.ripe.net is generally a secondary and hence it carries the information provided by the relevant primary, however if you fo feel there Is a problem with the information that ns.ripe.net is serving then please let me know the specifics and I'd be happy to look into it for you.
Brett
Brett,
here are some examples:
193.197.192.11 195.30.231.17 212.227.85.10
Every /16 has ns.ripe.net as one secondary. But only the servers of the corresponding LIR will give you the NS records of the /24. E.g. try
dig ns 192.197.193.in-addr.arpa @dns1.belwue.de
and than
dig ns 192.197.193.in-addr.arpa @ns.ripe.net
So its like playing roulette for our resolver.
Christian, as far as I can tell (without having access to the relevant servers) this is possibly a misconfiguration on the primary. I've taken a look in the zonefile we have for 197.193.in-addr.arpa and there is no delegation for 192.197.193.in-addr.arpa within that file so ns.ripe.net does not know where to send you. My guess is that the LIR have the child zone configured on their server and that is why they are answering differently.
