Redirecting Requests

Hi all,



I have a subdomain (applications.mydomain.com), and a private server (60.50.40.30) which runs an IIS6 webserver. What I want is that all requests send to applications.mydomain.com are sent to 60.50.40.30. What kind of DNS record do I need to create?



Also, I have created a website on my own IIS server with no IP specified, just the header field set to applications. Will that filter out the requests? Or do I need to set something else?

applications.mydomain.com. IN A 60.50.40.30
