How do I get a second IP address for my Arris T25?

First, check the "Rate Card" for your local area to see if that feature is even available anymore. Seems that it is being phased out;

It's a PDF.

Scroll down to "Xfinity Internet" and look for "Additional IP Addresses".

If nothing is listed then it's likely to have been discontinued in your local market area.

Greetings, @quicksilver2! I appreciate you taking the time to reach out to us here on the forums. I hope you are having an amazing day! I can certainly have a look into the account and see if we offer a 2nd IP address in your area as it's not available nationwide. Since you have already sent a PM, I will continue to assist you through there.

Thank you to @ComcastMichael and @EG for helping me get the second IP up and running on my account.  I can't say enough good things about what a pleasure it was to work with you both.

My pleasure ! Take good care !

Hello,

@ComcastMichael was able to successfully set my second IP address for the use on my second port on my Arriss T25.  Unfortunatly, it is not working now.  How can I get this working again?

Thank you!

Hello,

This was successully set up, however a week ago somone at Comcast disconnected the port.  Can someone help me get it working again?

Try sending a PM to .@ComcastMichael again.

Do you know if there is any number I can call for help or do you suggest I wait for @ComcastMichael ?

Thank you.  I reached out to him last night but have not heard back.

Calling customer service will likely get you nowhere. I would wait. He is a specialist, not a tier 1 rep !

Thank you.  That will spare me the frustration that occurs any other time that I call.

Thank you!

Thanks, @EG .  I tried sending @ComcastMichael  a PM last night but I haven't heard back yet.

It may be his days off. If you don't hear anything by the close of business tomorrow, I'll ping him again for you.
