To set up RDNS records for a Qwest.net business class network connection (mine is a DSL line), you must first log into Qwest.net using your account information. Next, select "Manage your account", then select "Configure your DNS Records" and finally "Configure Reverse DNS Records"
You would use this process regardless of if your donain's DNS records are hosted at a different provider such as your web host or domain registrar. In my case, our domain's DNS records were hosted on our web host's name servers. However, reverse lookups are a function of the ISP and not typically the name servers that are authoritative for your domain unless you've explicitly told your ISP to delegate RDNS authority to different DNS servers.
