Finding IP address of sender in gmail, yahoomail and hotmail

When you receive an email, you receive more than just the message. The email
comes with headers that carry important information that can tell where the
email was sent from and possibly who sent it. For that, you would need to find
the IP address of the sender. The tutorial below can help you find the IP
address of the sender. Note that this will not work if the sender uses anonymous
proxy servers.


First of all, the IP address is generally found in the headers enclosed
beween square brackets, for instance, [129.130.1.1]



Finding IP address in Gmail



  1. Log into your Gmail account with your username and password.
  2. Open the mail.
  3. To display the email headers,

    • Click on the inverted triangle beside Reply. Select Show
      Orginal
      .

  4. Look for Received: from followed by the IP address between square brackets
    [ ].
    Received: from [69.138.30.1] by web31804.mail.mud.yahoo.com

  5. If you find more than one Received: from patterns, select the last
    one.





Finding IP address in Yahoo Mail



  1. Log into your Yahoo! mail with your username and password.
  2. Click on Inbox or whichever folder you have stored your mail.
  3. Open the mail.
  4. If you do not see the headers above the mail message, your headers are not
    displayed. To display the headers,

    • Click on Options on the top-right corner
    • In the Mail Options page, click on General Preferences
    • Scroll down to Messages where you have the Headers option
    • Make sure that Show all headers on incoming messages is selected
    • Click on the Save button
    • Go back to the mails and open that mail

  5. You should see similar headers like this:






  6. Look for Received: from followed by the IP address between square
    brackets [ ]. Here, it is 202.65.138.109.
    That is be the IP address of the
    sender.
    If there are many instances of Received: from with the IP
    address, select the IP address in the last pattern. If there are no
    instances of Received: from with the IP address, select the first IP
    address in X-Originating-IP.


Finding IP address in Hotmail



  1. Log into your Hotmail account with your username and password.
  2. Click on the Mail tab on the top.
  3. Open the mail.
  4. If you do not see the headers above the mail message, your headers are not
    displayed. To display the headers,

    • Click on Options on the top-right corner
    • In the Mail Options page, click on Mail Display Settings
    • In Message Headers, make sure Advanced option is checked
    • Click on Ok button
    • Go back to the mails and open that mail

  5. You should see the email headers now.
  6. If you find a header with X-Originating-IP: followed by an IP
    address, that is the sender's IP address:




    In this case the IP address of the sender is [68.34.60.59]. Jump to step 9.
  7. If you find a header with Received: from followed by a Gmail proxy
    like this





    Look for Received: from followed by IP address within
    square brackets[].
    In this case, the IP address of the sender is
    [69.140.7.58]. Jump to step 9.
  8. Or else if you have headers like this





    Look for Received: from followed by IP address within
    square brackets[].
    In this case, the IP address of the sender is
    [61.83.145.129] (Spam mail). Jump to step 9.
  9. * If you have multiple Received: from headers, eliminate the ones
    that have proxy.anyknownserver.com
