NS lookup shows a different for domain ?

Hi

I registered a domain name with Godaddy and added a couple of namservers

ns1.domainns.com - 123.xxx.xxx.1
ns1.domainns.com - 123.xxx.xxx.1
These nameserver records were created on my own DNS server (Windows 2008)
I also setup an A record www.domainns.com --- 123.xxx.xxx.5

Tested the setup with URL's resolving to the IP address specified on my DNS server

After a week and a bit a ping test and nsloolup of my domain showed a different IP (belonged to  domains.theplanet.com)  

I went back into my Godaddy account to check the host records and the IP address of the ns records I created hadn't changed. Not sure how this happened.  Can anyone explain how this could be and how to stop it ???

Thanks

Did you run the IP at networktools.com?
Are you testing from an internal network only?
Are you certain you have reverse DNS authority delegated to you for that IP?

If the results from networktools.com, or any external DNS query, shows you the domains.theplanet.com result, then either:
A.  You don't have DNS authority of that IP from your service provider
B.  The old PTR record for that IP has a super-high TTL and hasn't expired from whatever cache you might be hitting.

Pasting outputs of commands you run while testing will make this go faster.

Goto networktools.com and put your IP into the box, leave the default Express search checked.

Double check things like A/PTR record, whois output -- make sure it all looks right.  If you see something there you were not expecting, paste it here.  Try to not sanitize the data too much.

I'm going to guess you didn't setup a PTR record to match your A record.  When you did the ping/nslookup tests that showed domains.theplanet.com, did you use the IP or hostname?  Is your server hosted at Softlayer by any chance?

I setup a PTR record as well  

Used the ping test first to see where the domain was resolving too and then did a nslookup of the IP address which went to domains.theplanet.com instead of my dns server ns1.domainns.com

The DNS is on a dedicated box in our datacenter.

Don't seem to under how this happened ?

I've had to turn of DNS services for the moment. But has this happenend to anyone before. Is there a security setting to be enabled on my DNS server
