forward DNS broken

[gimpbully]

I'm trying to figure out how one would go about getting forward DNS working.  Reverse seems just fine, resolves to a 

static.hfc.comcastbusiness.net address, but doing a forward on that address fails.  Any pointers?

Specifically, I guess I'm looking for a PTR.  Can anyone from comcast help?

Hello gimpbully,

Welcome to the forum.

Please send me the following information via private message, so I may assist:

1. Your Full Name

2. Your Account Number

3. PTR/RDNS entry (EX - aaa.bbb.ccc.ddd. --> mail.mydomain.com)

Thank you
