Now, the thing is NAME exist but either A or AAAA doesn't exist for this. Then how can a server reply that "no such name"?????? Thanks and Regards, Gaurav Kansal 9910118448 From: bind-users-bounces+gaurav.kansal=nic.in@lists.isc.org [mailto:bind-users-bounces+gaurav.kansal=nic.in@lists.isc.org] On Behalf Of Beisiegel, Sven Sent: Wednesday, 09 November, 2011 3:04 PM To: bind-users@lists.isc.org Subject: Bind does not reply with "no such name" to A query at Hi everyone, I tried to find a solution to this using Google, but I failed. I'm wondering if this is expected behavior of bind9 or if this is configurable. I have a domain configured and my server is the authoritative name server for this domain. My server is reachable via IPv4 and IPv6 address. 2 records are configured like this: dls-koe.gvs.local. 2h A 192.168.100.251 dls-koe-v6.gvs.local. 2h AAAA 2001:4dd0:f9c0:100::251 I have clients that are running with IPv4 and IPv6 address at the same time and are configured with one of the FQDNs above. When the client is sending a query for one of the names, it directly sends an A and AAAA query. Now for example: The client sends an A query for "dls-koe-v6.gvs.local", which is only configured as AAAA record in the server. I now would expect the server to reply with "no such name", but it doesn't. Other example: The client sends an AAAA query for "dls-koe.gvs.local", which is only configured as A record in the server. Same result. My question is: Why is bind not replying with "no such name" in this case? Is this expected behavior? Maybe a configuration issue? Thanks in advance for any help, Sven
