Home Office PHP Web Server : Reverse Lookup

[techlists at phpcoderusa.com]

Hi Amit,

Thank you for your feedback.  Cox is telling me I can do a reverse 
lookup myself.  The reverse lookup I am finding shows a subdomain I 
chose some time ago on a domain I own.

I was told Cox is getting out of hosting and DNS.

Is there anyway to determine where the DNS is coming from?

Thank you for all your help!!

Keith
