Re: Changing ip addresses for NS records

I did the same thing a few months ago. All you have to do is to notify
the registrar of the domain that the nameservers belong to, and of
course modify the nameserver addresses in BIND. If your nameservers
are

ns1.foobar.com
ns2.foobar.com
ns3.foobar.com=20

all you would need to do is go to your registrars website, modify the
IP addresses of the nameservers for foobar.com (name stays the same),
and modify the entries in the foobar.com zone on your master.

The SOA shouldn't be effected at all. The name of the box is staying
the same, ns1.foobar.com is still ns1.foobar.com, so the SOA will be
fine.

The only thing you should do (if possible) is to have the servers
answer queries at both the new and old IP addresses for some time,
that way if the registrar checks, you answer from the new address.

Peace,
Jim
