Hello all,
I'm running BIND 9.6.1-P1 on a Solaris box. This DNS (ns1.spx.net) is
authoritative to domain spx.net (this is just example). And I'm trying to
delegate nse.spx.net to ns1.nse.spx.net. I think I have configured correctly
but when I run a dig from a different DNS node for a subdoamin within
nse.spx.net like mil.nse.spx.net, it responds only SOA in the Auth section. Its
missing the NS from the zone files. The snapshot of my named.conf file
zone "spx.net" {
type master;
file "/opt/named/db.spx.net";
};
zone "nse.spx.net" {
type master;
file "/opt/named/db.nse.spx.net";
};
Here are the snapshot of consecutive zone files
$ttl 38400
spx.net. IN SOA ns1.spx.net. ns2.spx.net. (
1189784076
86400
3600
604800
38400 )
spx.net. IN NS ns1
spx.net. IN NS ns2
ns2.spxdns.net. IN A 10.1.2.3
ns1.spxdns.net. IN A 10.4.5.6
ns1.nse.spx.net. IN A 10.7.8.9
;there are other entries here
$ORIGIN nse.spx.net.
@ IN NS ns1.nse.spx.net.
And the 2nd zone file for submdomain nse.spx.net
$TTL 3600 ; 1 hour
@ IN SOA ns1.nse.spx.net <email> (
2008081812 ; serial
1800 ; refresh (30 minutes)
900 ; retry (15 minutes)
604800 ; expire (1 week)
3600 ; minimum (1 hour)
)
;
nse.spx.net. IN NS ns1.nse.spx.net.
ns1.nse.spx.net. IN A 10.25.130.75
Now when I run a dig for say mml.nse.spx.net I get only the SOA of the above
zone file and no NS information that the query is being delegated to.
#dig @ns1.spx.net mil.nse.spx.net
; <<>> DiG 9.6.1-P1 <<>> @ns1.spx.net mil.nse.spxdns.net

How would the querying DNS find out about the nameserver that this subdomain is
being delegated to? Why the query answer doesn't include NS sections. I've
tried to change few things but nothing works. The only information I get is SOA
and no NS in the AUTHORITY SECTION.
Any help would be much appreciated.
Thanks
Prabhat.
