How to Find an Email Sender's IP Address in Gmail

An email message contains more the just a message. It also contains the IP address of the sender which you can then use to isolate the single computer that sent the message, or even the city it came from. Gmail is no exception to this. You just need to know where to look to find it.

Step

Log in to you Gmail account using your username and password. Open the desired message by clicking on it.

Step

Click the small upside-down triangle next to the word "Reply" to view the message headers.

Step

Select "Show original" from the pop-up menu. A separate HTML document appears.

Step

Search through the text for the phrase "Received: from." A set of brackets delineates the IP address of the sender. If there is more then one set, use the last one.

Step

For example, if you see this in the text: Received: from [49.208.20.1] by web21504.mail.mud.yahoo.com

Step

49.208.20.1 is the IP address of the sender.

Step

If you want to trace the IP address to the city where it originated, copy and paste the address to Arul's IP address tracking program (aruljohn.com/track.pl). Then press the "Start Tracking" button. A map pointing to the city location subsequently appears.
