Are you claiming that the Comcast modem uses a different IP address for Comcast-network side of the NAT? That the modem has two routable addresses, one for the 'house', and one for the 'open' world?

Yes, that is generally/approximately correct. I'm not sure precisely how it's implemented on the public side, but you're placed into a seperate VLAN that enforces the captive portal. Traffic from the public WiFi network is isolated from the subscriber's traffic.

That does not mean it uses a different public IP address that communicate with the rest of the intermet, I have seen dozens of such public/private wifi systems, abd never seen one with a separate public IP

That doesn't at all answer GPs question though. That they're isolated LANs doesn't at all answer what WAN address they use. If no other indication it probably uses the same.

I have multiple VLANs at home, and I only have one WAN IP.

for what its worth: claims to have tested and says they are different public IPs

Okay, so what do you get if you lookup which customer is associated with the public IP?
