For one thing, the device you connect to probably won't be a computer but a cisco router. If the websites are virtual they may have a virtual IP address as well. They may however have a blade with it's own NIC device as well for each website if that site justifies that much traffic. Some are colo's where you have a physical computer on site with full control. Here you probably have your own nic device (and maybe a spare) on the their LAN side of the network.
