How to Find Someone's IP Address

By Foye Robinson

An IP address is the online pointer to a person's computer. It is recorded on Web servers when you're on the Internet. You can hide your actual IP address with a proxy, however, so the proxy's IP address displays instead of yours. Finding someone's IP address is tricky, but not impossible to do. You'll need to get the person to interact with you in some way to get the IP address. One of the easiest ways is through email, which saves the computer information with the message.

Gmail

Step 1

Log in to your Gmail account on your computer. Open the response email from the person.

Step 2

Click the arrow beside "Reply" to expand it. Select "Show original." A message header opens in a new window.

Step 3

Scroll to the "Received" line to locate the person's IP address.

Yahoo Mail

Step 1

Log in to your Yahoo Mail account on your computer. Open the response email from the person.

Step 2

Choose "Actions" then "View Full Header" from the drop-down menu.

Step 3

Check the "Received-SPF" line to get the person's IP address.

Outlook

Step 1

Open the person's email message in Microsoft Outlook.

Step 2

Choose "File" and then "Properties" to open up the Properties dialog box for the selected message.

Step 3

Go to the "Internet headers" section. The person's IP address displays under the "Received" line.
