we had a guy look at our slow network and show us the ip addresses and who was using the most bandwidth.  It also showed internet addresses.  One of them was right at the top of the list.  Using the most bandwidth (I think)  How would I find out what site this is?  I tried to type in the number but nothing happened.

Is this limited to web traffic?

Also, the text doesn't mean that the top two are necessarily the ones that are talking.  192.168.0.14's traffic could very well be small connections to several sources.

If you really want to find out, ask them to run the trace for that specific pc, and with port numbers.

"68.142.122.70" is "cdn-68-142-122-70.dal.llnw.net" looks like a DSL/Subscriber address on http://www.limelightnetworks.com/.  They're worldwide.

IDserve from GRC.com will let you look up IPs and URLs to get some info.

Standard software for packet tracing would be one of these:

WireShark (formerly ethereal) - http://www.wireshark.org/
Microsoft network monitor - http://www.microsoft.com/downloads/en/details.aspx?FamilyID=983b941d-06cb-4658-b7f6-3088333d062f&displaylang=en
tcpdump

Setting them up if you're not familiar with the network can be tricky though.  Essentially you need to run this on a computer that's between the offender and the internet connection.  Typically this is done via a port map on your firewall/switch.

Still though, probably the easiest way to find out is to log into the machine and look.
