>What happens if your ISP changes your IPv4 address?

Absolutely nothing, because the private IPs behind the NAT are agnostic of the public IP.

Actually, all your open connections break (including outbound ones, inbound ones via UPnP which is commonly on by default, etc.)

  • No, my connections time out for a brief period of seconds or minutes and then everything is fine for the next two years (until my ISP cycles my IP out again) and I don't actually need to do anything to resolve this. I wouldn't even know when my IPv4 address changed because the impact is so minor. uPnP may be on by default but that doesn't mean most people are actually using it for anything.
