How to find the IP Address of the E-mail Sender

Dear Friends,

Let me ask you a very simple question first.

How do you determine where an email message actually came from?

Most people would say "By the From Line."

NO, This is not the accurate approach to get the address of the sender.

With the help of below mentioned example you’ll get to know how to find the IP of email sender.

{Note- This will not work if the sender uses anonymous proxy servers.}

Finding IP address in Gmail

(1) Log into your Gmail Account with your Username and Password.

(2) Open the desired mail from Inbox.

(3) To display the headers:
    Click on More Options corresponding to that thread. You should get a group of links.
    Click on Show original

             

(4) You’ll get headers like this:

Delivered-To: myXYZemailID@gmail.com

Received: by 10.216.178.16 with SMTP id e16cs126934wem;

        Wed, 18 Jan 2012 11:48:09 -0800 (PST)

Received: by 10.50.161.135 with SMTP id xs7mr8095971igb.15.1326311286088;

        Wed, 18 Jan 2012 11:48:06 -0800 (PST)

Return-Path: <bounce.senderID@gmail.com>

Received: from mailer.senderID.com (mailer.senderID.com. [202.89.73.131])

        by mx.google.com with ESMTPS id ur7si3226619igc.19.2012.01.11.11.48.05

        (version=TLSv1/SSLv3 cipher=OTHER);

        Wed, 18 Jan 2012 11:48:06 -0800 (PST)

(5) Look for Received: from followed by a few hostnames and an IP address between square brackets.    
      Here, it is 202.89.73.131.

      This is the real IP address of the sender!

(6) In your email header, track the IP address of the sender. Got it!

That’s all.

Wait for more tutorials on IP Lookup in the near future.
