Will you've got it a little wrong.
Swtiches have 5 ports, nothings assigned. It'* basically splitting the cable, into indivudual devices. The ISP will see everything hooked up to it.
A router splits it like a swtich, and normally adds a gateway, with NAT. This way, the uplink is one network, and the LAN is another.
If you plug a Switch into our ethernet drops here in the dorms and add 4 computers, they'll each have their own public IP. If you plug in a router, and register one computer, that Information is setup on the routers settings, and the ISP will only see one Public IP.
