How to Find Someone's Location by the IP Address in an eMailby Contributor
One of the most requested information online regards how to find where someone lives, or their approximate location by identifying their IP address. Some companies will charge you for this, but the information is available for free online, if you know how and where to look.
Open the email in question.
View the headers of the email message. This is straightforward in most email programs, and you can click "with headers" or "full version" to view the behind-the-scenes code that will tell you where the email originated. For Google gmail users, read this eHow article to learn how to view headers: http://www.ehow.com/how_4604962_address-email-youre-using-gmail.html
Once you've found the sender's IP address, you're ready to find out information about the ISP (internet service provider) that they used to send their email.
Go to ARIN (the American Registry for Internet Numbers). Their site is located at www.ARIN.net.
Put the IP address you're researching into the search window, and click "Search WHOIS."
You now have the name of the ISP who owns the IP address that the sender used to send you the email.
While this information may not always be 100% accurate (such as if a person lives in a small town, and has to use an ISP in a neighboring larger city), you will get a good idea of what part of the country the email originated from by identifying and researching the IP address on emails they send you.
- If you are being harassed via email, keep save the emails. You should also print out the email along with its headers, just in case something happens to your computer. See law enforcement or seek legal counsel as soon as possible.
