How to Find out Original IP address of email was sent

Post by balaexpress » Tue Jun 20, 2017 11:44 pm

How to track an email to its original IP address i.e When we read an email Header only can able find out Public IP address of the particular organisation / Institute. Under this Public IP address we have connected no. of Computers through Network by using DHCP.(same like WiFi Network).

Here my questions is How to find out the Original IP address (i.e local IP) of that particular computer a email was sent.

Kindly give me the suggestions (to find out local IP, Is there any software or hardware device? ) regarding this.

It's going to depend on mail server is configured. It's a matter of looking at the headers to see if it's there.

Code: Select all

Received: from mail.example.net (mail.example.net. [66.171.248.x])
        by mx.google.com with ESMTP id m11si2067394pfa.98.2017.06.21.07.31.01
        for <example@gmail.com>;
        Wed, 21 Jun 2017 07:31:01 -0700 (PDT)
Received-SPF: pass (google.com: domain of example@example.com designates 66.171.248.x as permitted sender) client-ip=66.171.248.x;
Authentication-Results: mx.google.com;
       spf=pass (google.com: domain of example@example.com designates 66.171.248.x as permitted sender) smtp.mailfrom=example@example.com
Received: from [10.0.0.131] (76.224.168.x) by mail.example.net with
 ESMTP (EIMS X 3.3.9) for <example@gmail.com>;

In this example you can see the LAN IP [10.0.0.31] and the WAN IP (76.224.168.x) received line as the mail server records the handoff from the client to the mail server.

Yeah, when sending from a gmail account to another gmail account no user's IP address will be exposed.
