Email Tracing Tips

Each electronic mail(e-mail) you receive comes with headers.You can see that no matter the email program, the headers are usually just a right click away. The headers contain information about the routing of the email and the originating IP address of the email.

IP address is a 32-bit address used to identify a node on an IP internetwork. Each node on the IP internetwork must be assigned a unique IP address, which is made up of the network ID, plus a unique host ID. This address is typically represented with the decimal value of each octet separated by a period (for example, 192.168.7.27).
Usually the first IP listed is where the email originated. There are exceptions to this. You'll have to look at the information logically to deduce the originating IP Not all emails you receive can be traced back to the originating point and depending on how you send emails determines whether or not they can trace the email back to you. The headers don't contain any personal information. At most, you can get the originating IP and the computer name that sent the email. The originating IP can be looked up to determine from where the email was sent. IP address location information does not contain your street address or phone number. It will most likely determine the city and the ISP the sender used.
