Getting an IP and connection is more complex than that but already we're down to a series of routers.No, they'd use private VLANs with the default router in a promiscuous sub- VLAN. That way they won't have to waste 4 IPs for every customer. Customers with multiple IPs can be put in community sub-VLANs, if they pay for it. Networking works very differently within Service Provider networks.
