Today one of my friends asked my helps on tracing or finding out another people’s IP address. He indicated this guy(s) had his Yahoo! Messenger account and email address from some ways, then started to harass him in instant messages and emails with nasty words and graphics. My friend tried to know who this “bad ass” is(are) and where he(they) is(are) from. So a basic IP will be a starting point.
After researching and testing, I offered him some tips to find out the IP addresses from emails and messengers. But I could not guarantee the accuracy of my recommended ways since IP addresses alone could not identify anyone, especially dynamic IPs, ISP routers, and proxy could be used at the another end. So the best way is to report to the law force team and let them co-operate wit ISPs if the damage is serious. Of course, you can try these recommended ways to find out some information first anyway.
How To Find out IP addresses of sender from Emails
The email header will be the best way to see information about the email sender.
In Outlook, open the email from the suspicious person, then go to View and Options…, you will see the following windows. And the important information of sender will be in the box of Internet headers:.
If you are using web mails like Yahoo! or Hotmail, you can turn on the advance options to see the header from sender. The detail instruction can be viewed in different Web Mail help documents, or you just simply play around in your inbox.
How to find out the IP in MSN messenger
First, launch a DOS command window. In Windows, you can hit Start and then Run, and type CMD in the Open field. In the command prompt window, type netstat -n or just netstat to be familiar with this connection command. The result will display all Active Connections running on your machine, and will have four columns like the below.
Protocol Local Address Foreign Address State
And the Foreign Address is what you are going to look at.
Second, launch your favorite instant messenger and waiting for the bait. If the guy you tries to trace goes online and starts to chat with you. Think hard to establish a direct connection with him (her) first. Because all text chats are proxy from Microsoft server, only direct connection can expose other side’s machine IP.
There are a few ways to do so: like 1) file transfer; 2) video/audio chat; 3) link to your own web server. In this example we just use file transfer. Remember, when you use file transfer please use a large file (at least large than 1024KB) to force the direct connection and buy you more time.
Last, run netstat -n command again in your DOS command window when or after the file transfer. Normally, the second netstat command can show the new connections with other machine’s IP. The port number can be anything between 1000 to 3000. Just compare with your first netstat command result to recognize other side’s IP address.
How to you do after you have the IP address is not my business any more (at least not in this post). You can do reserve DSN lookup or call the authority. Just hope you have the luck to track down the person you wish to trace, good luck!

It sounds like you’re creating problems yourself by trying to solve this issue instead of looking at why their is a problem in the first place.

Search engine optimization or seo is a thorough process that involves checking the site for errors, improving titles and metadata (i.e description) and of course the offpage part of the process meaning a lot of links. This is called linkbuilding and it’s probably the hardest part of the whole seo process. Oups I forgot it’s very important to use canonical url’s through a 301 redirect.
