I need a public reverse DNS / PTR update for my static IP.

Please change:
[Edited: Personal Information] -> [Edited: Personal Information].

Please remove the current additional PTR records for [Edited: Personal Information] if possible, so that only this PTR remains.

Forward DNS is already in place:
[Edited: Personal Information]. A [Edited: Personal Information]

This IP is my outbound mail server, and the PTR needs to match the SMTP hostname.

Account details:

Name: [Edited: Personal Information]

Business name: [Edited: Personal Information]

Phone or account number: [Edited: Personal Information]

Account number: [Edited: Personal Information]

Please confirm when the change has been submitted or completed.

Thank you for reaching out. I ask that you reach out privately, so we can cover the details of your account. You can start by clicking the chat icon located in the top right corner of your forums page when signed in. Once there, you can direct your messages to "Comcast Business." Please add your full name, service address, and account number to help us locate your account. Let me know if you have any questions.
