I have a questions on figuring out the IP address of people sending me emails on my gmail account. Gmail wont let me get the IP address of Gmail users who send me emails. I had 2 people email me today and I suspect its the same person. How can I tell if they sent the messages from the same computer/network or same browser?

Here is the info when I click Show original. I deleted some info identifying the sender.

Header #1 or the top one shows: Received: from mr.google.com ([10.216.143.223])

Header #2 or the bottom one shows: Received: from mr.google.com ([10.236.176.232])

They aren't the same exact IP but from the same domain.

Cool. So what is that supposed to mean? Does that mean they could have came from different browsers on the same computer? A different computer on the same network?

Supposedly both came from people living in the same area but not at the same place during that time.

From that information alone it's impossible to know. Thats all you have to go on with an email header. The emails came from the same domain. Thats as good as it gets with the information provided. Sorry.
