Interesting. It's an extension of NAT.
So you would have to purchase a pool of external IP addresses from your ISP?
So, technically, if you had PAT on your home router, which I'm not even sure is a thing, and purchased external IPs from your ISP, you could cheat Reddit's IP ban, assuming they actually have an IP ban in place?
But regular external IPs get cycled every few weeks/months, right? So wouldn't anyone with a Reddit IP ban be able to get back in with a new account once their external IP naturally cycles?
I mean if Reddit banned based on more than IP, like my computer's MAC address, then any new account I created would be insta-banned for having the same MAC. I've been using this same computer for a few years now.
