How to check an IP address on Yahoo

If you're getting emails from someone, and you're not sure who it is, you might be able to find out by getting the sender's IP address. This is fairly easy to do if you use Yahoo! Mail. You'll need a Yahoo email account with an email in it from the person you're trying to track. Whether you're trying to find someone that you've lost touch with, or someone is harassing you, getting the IP address can help you track this person down.

Use the sender's email to find out where he is.

Step

Log into your email account. Go to the the email that was sent to your account, and click to open up the email.

Step

Enable the full headers of the email. Toward the right of the screen at the top, you see an "Options" or "Actions" button. Click on this button. Depending on your Yahoo! screen, you'll either have to click on "Mail Options," go to "Messages" and click on "Show All Headers," or you can simply click on "View Full Header" from the drop-down screen. This will open a dialogue box that lists the IP address.

Step

Find the IP address. The sent email should have an IP address; however, some people do block IP addresses on emails. Look for the name of the person who sent the email and the date, usually next to the word "Received." Look for a four-sectioned number, such as 86.50.353.136. That is the IP address. You may have to read through a few lines to figure it out.

Step

Copy the IP address. Highlight the IP address, and then right click on it and click on "Copy."

Step

Do a reverse IP address search. Go to a search engine that does revers IP address searches. See the Resources section for links. You can then run an IP address reverse check. Simply right click in the search box, and click "Paste" to add the IP address. The search engine will give the IP host's name.
