Confusion Regarding IP Addresses in Header

Hello,

I'm confused.

There are 2 "X-Originating-IP" addresses (207.115.11.55 and 68.19.237.34) in the header below.

Is the first one the att.net server ..... and the second one, the IP of the user's local machine?

Is that correct? I'm completely guessing.

Thanks.

Code:

Received: from [I]xxxxxxx[/I].isp.att.net ([[B]207.115.11.55[/B]])
          by [I]xxxxxxx[/I].comcast.net (sccrmxc23) with ESMTP
          id <20070916155719s2300sn5dpe>; [I]date[/I]
X-Originating-IP: [207.115.11.55]
Received: from [I]nameid[/I] (adsl-19-237-34.bna.bellsouth.net[68.19.237.34])
          by bellsouth.net (frfwmhc05) with SMTP
          id <20070916155716H0500qlj85e>; [I]date[/I]
X-Originating-IP: [[B]68.19.237.34[/B]]

 

That would be a mail server ip, not the end users ip.
