Changing the public IP address

I'm pretty certain my home's IP address has been publicly exposed, so I'd like to nip any potential issues from that in the bud and have it changed. I have tried to contact Xfinity support, but they've been predictably useless and just directed me to this article which has nothing to do with the public IP address: https://www.xfinity.com/support/articles/releasing-and-renewing-ip-address

I need to change the public IP address, not the local one that this guide applies to. I have a standard xFi Gateway box, "Voice and Gateway Modem"; Is there anything I can do through it for this that actually works (no, powercycling for a minute or however long does not work)? Are there any actually useful support personnel that can reassign an IP? At worst, would buying my own router do the trick?

Hi! I'm not an official support but I'd like to offer my help!

Absolutely you can change your external IP address as you are not
paying for a static IP address that means you are on a dynamic IP address.

To change your external IP you need to swap out your Xb7 in the store or

Bridgemode your Xb7, connect your Xb7 to a router, configure router to show
up as PC MAC address instead of looking like a router so Xfinity doesn't deny your DHCP request,
and then presto in about 10-20 minutes and maybe with just one power cycle of your main modem

You'll be handed a new external IP address by Xfinity DHCP.
Special note: New IP [Edited: "Inflammatory"]

I personally have to swap and reactivate my equipment every time I want to use
my service regardless of how much data I have used!

I'm offering support to all other cases hoping someone looks at mine.
