Q:
Determine Internet connection type from originating IP Adress
IP addressing, Email origination, SMTP header analysis, Email
I have read that there are some "IP Address Locator" websites, that when you enter the Originating IP Address from the emails Return Path, it will be able to tell you the internet connection type that was used to send the email. Can anyone point me to the website that can do this?

I don't think you can tell internet connection type from the sender's IP address. You can tell the ISP from the address and maybe then figure out if it is a cable, dsl or TDM type of connection. However, remember that emails can take several different hops before getting to your mailbox. The ISP could be using a network of email relay servers. The email client could submit the message to one server locally and then it get rerouted through the ISP network and go out a different server entirely. You would need to look through the entire header to trace the message path. Just looking at the last IP address does not give you the whole story. A good website for SMTP header analysis is http://headertool.apelord.com/

I don’t know of such a site.

I think there is no way to know the connection type that was used in the past, when the e-mail was sent just by the ip-address.

This is the ip address locator I use. It can give more information when you are tracing your own address.
