I think Dr. Hyatt was talking about a NATed firewall, which is different than something like Zone Alarm. For instance, at my house we have cable internet connected to a router (little thing, looks like a hub), and we have four or five computers with network cables plugged into that. One thing the router does (among many others) is that to anyone on the internet, all of our family's computers have the same IP address. The router sorts out the details and makes sure the right data gets to the right computer at our house. This is advantageous to us since we only have to pay for one IP address instead of four or five. Now imagine a company that "hides" hundreds or thousands of computers behind one IP address. There's no way of knowing which one of the thousand computers a message came from. >Also what is IP 127.0.0.1, I assume it's a blank IP but would CCC give you an ID >using such an IP?. Naturally they could avoid that and only issue ID's to valid >IP's. I'm probably getting over my head anyway as I know little about how you >could fake an IP. 127.0.0.1 is a reserved IP address, called the loopback address. Essentially it is a way to refer to your own machine. It is useful for troubleshooting network problems. If you can ping 127.0.0.1 successfully, then you know you're network card is working at least, even if you can't connect to anything on the network.
