Looking for help in getting a second IP addess for a Sb8200 cable modem I own.
I have seen some other threads on this but nothing that is a step-by-step preocedure.
Any help is appreciated.
There is no "step by step procedure". 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.
