How 2 monitor up/dnld destinations/sources

I use a Verizon wireless data card with ability to monitor upload/download traffic through Verizon's VZ Acess Manager. I am watching traffic on the Manager without any browser program running.  At the msdos command line & netstat -b, the Verizon ip address for source & foreign connection - but no other ip address. Verizon techs state that the foreign ip address is just a Verizon gateway.

 

How can I find out what the source of the download is & where it is being downloaded to in my computer? It might be a legit update,,, or not. I am running Symantec 360 & have all on.

 

Is there software out there that will list ip addresses with owners info real time as it is being transmitted/received?
