How do you trace the e-mail address from it's IP address?

Someone is harrassing me, and yes, I have the IP address but not the e-mail address. Is it possible to find out the sender's e-mail address using the IP? If so, how? Please and thank you.

How do you trace the e-mail address from it's IP address?
I'm assuming they are sending you emails with a fake email address? You would have to contact your email provider and get them to run a tracert ( traceroute ) to make sure you even have the right IP address and that still won't give you their personal email address as they are using a program and not say a normal email provider. But once they find out where the emails are coming from then you can complain to their service provider. Honestly ive done it before,but i telneted into a shell account on the web so you couldn't even get my IP unless you went deep and got the ISP or FBI involved.
Reply:Received: headers are sometimes helpful, but spammers and hackers can add extra headers to confuse you. The geo location tools recommended in other answers will help locate what city that IP address comes from.





However, unless the e-mail came from your work or school, it is unlikely anything can or will be done about harassing e-mail. The cost of tracking down the offender and the likelihood of proving who sent it is too expensive and nearly impossible. Just because you can prove what computer an e-mail message came from does not mean you can prove who was behind the keyboard sending that message.
Reply:Don't listen to the first answer he don't know anything about computers. Go to www.ip-adress.com and click on trace ip at the bottom. Click on view full headers on yahoo email find the xoriginating ip or received from ip. That's how you find the ip address and trace it. If any top contributors are stalking me I will report you to the fbi. www.ip-adress.com is the place to trace an ip address. you have to leave out the second d.
Reply:Im afraid not, unless the user has their own mail server, then you will be able to trace.





If you use hotmail or gmail to send an email it will be their IP not yours. The person sending's IP will be stored in the email account suppliers logs.





Hope This Helps
