Reverse DNS

Hi.  I need a reverse DNS entry made for an IP address.  Who do I contact at Comcast for this?

I hate to necro a thread but i've been on the phone with support for a week trying to get a PTR/DNS record setup for my static IP. I've DMed the "Comcast Business" with a blue checkmark that shows member since Dec. 13th 2020. How long does it take for a response? Not sure what comcast recently changed but our reverse DNS now shows no domain and has kicked our email server onto many providers reject lists.

Welcome to the Xfinity Forum and thank you for posting your question here.

Thomas, I'm trying to get a PTR record setup for one of my static IPs. I've already contacted my alternate ISP and had this taken care of in about 10 minutes. I've been on the phone with business support for a week now and haven't been able to accomplish this task. I've been promised multiple callbacks that never happen and been assured that my issue has been escalated to tier2 but no one seems to know who/where tier2 is  only that tickets go to them. This is causing quite a bit of issue with one of our servers and i'd like to get this resolved ASAP as upper management gets testy when the email doesn't flow.
