I would like to get an additional IP address added to my residential account. I have the Xfinity Dual Band802.11ac router. How do I add an additional IP address? I called Xfinity customer service and the person I spoke to did not know if this was possible. Do I need a VPN? Please explain the process. Thank you.
What is the exact make and model number of your modem ? It sounds like it is one of those combo modem / router gateway devices. If it is, you can't get a second public / WAN IP address for it.
