dig server problem

[Pedro Espinoza]

have changed the IP address of one of our name servers (ns1).
ns1 old IP is x.y.z.130; now ns1old is the hostname for the old IP, x.y.z.130
ns1 new IP x.y.z.150

on ns1:

When I do, nslookup ns1, I am getting x.y.z.150 (no problems at all).
When I do, host ns1, i am getting x.y.z.150 (no issues at all).
When I do, dig ns1, i am getting x.y.z.150 (no issues at all).

When I do, dig @ns1 ns1.ourdomain, I am getting the proper A record in
the answer question.

However, I am getting FALSE information in the comments.

The @ns1 is leading to old IP address. Any suggestions?



My resolver.conf is perfectly fine. I even changed keep_hot_count
hosts to 0 in nscd.conf, and bounced that daemon.

Even the reverse lookup of x.y.z.130 is giving me ns1old.domain.
