Ticket Number: [Edited]

Hello,

My request to set up a PTR record was marked closed, but when I check:

dig @8.8.8.8 -x[Edited: Personal Information]

It returns no results (NXDOMAIN).

The forward DNS works: proxy.chicopmr.org →[Edited: Personal Information]

But the reverse DNS (PTR) is missing:[Edited: Personal Information] → (nothing)

Can you please verify the PTR record was actually configured on your end?

Thank you!

Thank you for reaching out to our team here. I will be happy to take a look at that ticket from here. Can you send me a direct message with the full name and complete address for the service? 

To send a direct message [private message]:

   Click the "Direct Message" icon or

   Click the "New message" (pencil and paper) icon

   The "To:" line prompts you to "Type the name of a person". Instead, type "Xfinity Support" there.

   - As you are typing a drop-down list appears. Select "Xfinity Support" from that list.

   - An "Xfinity Support" graphic replaces the "To:" line.

   Type your message in the text area near the bottom of the window

   Press Enter to send it

Hello John

When I enter a value in the To line it will not accept Xfinity Support. My last DM was sent to Comcast Business and it does contain the full name and address. 

Other suggestions?

You are welcome to call the phone associated w/ this a ccount.

Hi @user_7379ce. Thank you for reaching out. That would not have been us calling as we would need some additional information. Instead of messaging "Xfinity Support", please send a direct message to "Comcast Business". You will see a blue checkmark next to the name. Please provide your full first/last name, complete service address, and the rDNS/PTR record information so we can submit a request. We hope to hear from you soon.

I just DM Comcast Business. It looks like just a continuation of my last DN exchange even though I clicked the Add/New icon
