1194143 2011-04-23 08:20:00 Yes it's the modems IP, but it's the account holder who will be charged, they don't care who was using your connection. Also, there has to be information in the packet so it knows where to direct the information, the router isn't "magic". What happens if two PC's are visiting www.google.com at the same time? It has to know how to send which information to which PC... Chilling_Silence (9)
1194144 2011-04-23 10:41:00 Speculation : I don't think ips of computers are on the internet , it's the modem's ip [which can't be changed?] . Also i'm sure the modem has to connect to the ISP's server/modem before the internet -for billing purpose , so they can track any change you have made to the IP addresses?
The modems IP is usually assigned by the ISP when you first turn it on or if it is reset.

With NAT there is not usually any info in the packet that identifies the internal machine (which is invisible to the world anyway).
The replies from external servers return to the same port the outgoing requests were sent from (typically high ports ~50k-65k depending on router OS).
The router's masq table keeps track of which connection belongs to which internal IP and the router forwards the packets accordingly.

+1 the local router keeps track of the port numbers and which internal PC they belong too, its not possible to identify machines on the inside of the Nat externally by port numbers.

My how IPv6 will change all this :P

OK that's good to know. Unfortunately I'm not a guru when it comes to NAT, I just know that it *is* possible with VoIP (SIP / RTP), though it could be protocol-specific stuff that's including the LAN-IP Address.

That article on Stuff was a good one. I can see the hard part a lot of people will now become afraid of being "Is this copyrighted materials I'm now viewing?".
