Reverse look-up returns root servers?

I'm inksystems.com

the vendor is apollocolors.com

I reloaded nscd and named, and sent an email to purchasing to have them check it again. I'll also ask her to forward the information to the vendor to sync their TTLs and make sure they add the other name servers, I wonder if their changing over and that's the issue? 

Thanks,
