MY IP ıs routing to old address !!

Hi

I asked about rDNS yesterday because I am having problems the DNS for my server.

I initially set up my server with the main account as heavyhoster.net My registrar is opensrs.net and I set up a record with them to point to my two IP addresses.

i.e. ns1.heavyhoster.net -- > 65.23.129.163 ns2.heavyhoster.net -- > 65.23.129.167

After a year I decided not to use my .net domain and to just use my heavyhoster.com domain.

So I changed over all the settings in the BIND and also set up ns1.heavyhoster.com -- > 65.23.129.163 ns2.heavyhoster.com -- > 65.23.129.167

That was all done about 1 month ago.

My problem is that when I use a site like "network-tools.com" to chack my DNS I get this reply:

"Retrieving DNS records for heavyhoster.net... Attempt to get a DNS server for heavyhoster.net failed: heavyhoster.net does not exist in the DNS"

So it finds the old records that should be deleted by now.

Is this a reverse DNS problem or a problem with opensrs.net ?

The above are real IP values so I would appreciate it if someone can check out the resolution - maybe "network-tools.com" is not the best site to use ?

Thanks
