And the IP address of that 'gateway' [1] is used in routing tables
containing IP addresses that can be traced right back to your computer.
If an IP address could not be traced back to a machine somewhere
the Internet would not even function!

*ALL* IP addresses -- world-wide -- are assigned and managed by
IANA (Internet Assigned Numbers Authority) [2].

*ALL* IP addresses that have been entered into the routing tables
can be traced back to somebody using them. All that really matters
is the motivation and the resources allocated to do so.

Anybody that wants to believe Jim Cheshire's misunderstanding can
test his 'hiding behind a gateway' fallacy by using a computer to
download child pornography or commit some other serious crime.
I do not recommend doing so however as letting me know I was right
after all would have to be done with pencil and paper while sitting
in a jail cell.

I might add that the RIAA has been tracking those who download
music by using the IP address as documented by the Electronic Frontier
Foundation [3].

In at least one case RIAA has been able to use the IP address to
identify and prosecute a user for downloading music. Apparently
only because the ISP who had been assigned the IP addresses
chose to disclose the identity of the user whose machine was using
that particular IP address.

If those ISPs were not using dynamic IP address assignments that are
resolved behing their firewalls using the IP address to identify the user
on any machine would be a piece of cake. Thus, 'reliability' is somewhat
of a misnomer in this context. Using IP addresses has become common
in e-commerce to help determine which country the request is coming
from as IANA allocates certain IP address blocks to different nations.
Again, using the IP address for some objective is all a matter of
motivation and resources.

I think these comments should be sufficient to respond to Seņor Cheshire's
hiding behind a gateway fallacy.
