Hi, I've got a newbie-to-DNS-registration question.   How do you register a URL address to point to a server / DNN site that doesn't match the server name that the site is hosted upon?   
Example:  hostname PROD  is already setup with fqdn:  PROD.mydomain.com and this machine has a dotnetnuke site called DNN.   So from the DNN site is accessible as prod.mydomain.com/dnn 

But, if I already own domain www.abc.com and want it to point to the root of my DNN portal?  i.e. How can I make the URL www.abc.com point to prod.mydomain.com/dnn ? 

Thanks in advance

Thank you - this helps, but since I'm new to DNS-stuff, the leads me to more questions:
 1. Is the name server different from DNS?  or a part of it? or ??

2. Also, my office has a dedicated T1 directly to the internet, so in this scenario I'm not sure there is a 'host provider'. 

3. For your other suggestion, (redirection on the hosting server), where is that configured?  is it the hosts file?  or some other config file?  if it is some text file, could you post an example of how that would be setup?

Sorry for such basic questions... -- I appreciate the tips.

This is also referred to as "domain forwarding". My domain name is managed through godaddy.com and I either forward to my IP and use masking to show my domain name instead of the IP, or I can forward my domain name to any other domain name. It should be that easy for you.

EDIT: I believe that masking a forwarded domain breaks DNN. DNN doesn't know how to resolve the masking and just returns to the page without login processing. You can remove masking from a forwarded domain and get it to login just fine, but then your IP shows in the browser for the URL, not your domain name. It is my opinion that we must move DNS from our host to some other host such that we can edit the DNS record to show the domain name instead of the IP without masking (without forwarding too). I have only theories at this point.

Keep the faith.
