If I understand IP addresses properly, they cannot be faked, as a residential address can. I understand the each computer has a distinct numerical code when connected to the internet. This unique code cannot be faked. Such codes have been used to trace criminals, particularly purveyors of kiddie porn.

I think you may be talking about the MAC address in the actual hardware, not the assigned IP address. If I’m not mistaken, even those numbers can be spoofed/masqueraded also.

The IP number that a web site sees can easily be faked by anyone. It is not the number that is uniquely linked to your physical computer.

There is free software that anybody can download and install. It randomly assigns an IP number that can orginate from anywhere around the globe. I've used it to try it out and it works great.

So, using this TOR software a single person in a single location can appear to be sending from anywhere in the world, no problem.

I think you mean the MAC address. The IP can be changed, but a MAC address is constant
