Reverse DNS Issue: PTR record missing

Xfinity is my ISP in both Colorado and Florida.

A Reverse DNS Lookup on the IP address assigned to my Colorado Gateway works fine.

However, the Reverse DNS Lookup on the IP address assigned to my Florida Gateway fails (No Domain found).

How do I request Xfinity to setup the PTR record for the IP address assigned to my Florida Gateway?

Thanks in advance,
