Re: Can ANYBODY help resolve this debate?

In the case of pop3/smtp mail originating from behind a router implementing
NAT--network address translation--which describes the vast majority of
home/small office routers these days--the same IP address will be in the
headers of the message regardless of which workstation behind the NAT is the
originator.

This may be enough for you--i.e. within the same home or small office might
be sufficient for your purposes--but perhaps not. A nat can theoretically
have 256 client machines, although most are more likely on the order of
between 2 and a dozen or two.

Hi all,

I have a general research enquiry regarding IP tracking and wondered if
you
might be able to help?

I am currently following a debate regarding the claims of 3 apparently
independent sources via an e-mail list and website. Information has
recently
been disclosed which shows a correlation between IP addresses.

One side of the debate argues that the IP correlation is 'proof positive'
that these 3 individual sources are in fact one person with 3 e-mail
accounts.

The other side 'counters' that the IP addresses belong to the mail server
andcannot be used to identify individual machines.

If you are able to resolve this debate I would be very grateful, if not
could you possibly refer me to someone who can?

To reiterate my questions:

1. Is it possible to identify an individual source from IP data?

2. If apparently independent e-mails repeatedly originate from the same
IP's, could this indicate that they are, in fact coming from the same
source?

With your permission I would like to post your response on the forum at, I
will of course reference the website and remove any names if required.
Thanks
for your time.

Kind regards,

Lee Nicholson.
