Okay, any given IP address has four nodes:
What does each node represent?
Let's say I want to relate or demostrate that multiple emails came from a common location. Let's say I have a sample of emails in which some of the firt two nodes are the same. Do I have anything?
My goal is to try to tie a handful of these messages (from an unknown sender but with an originating IP and sever trail) back to a known sender using a different email address but possible a laptop computer and a wifi connection. The goos thing here is that I have several samples from several locations and I think a few of them may be the target wifi point as nodes 1 and 2 match.
What more can I do by reading message source code?
