One thing I might be tempted to try would be to execute a trace route utility and analyze the output, but it is very cryptic; http://www.traceroute.org/ http://www.tracert.com/cgi-bin/trace.pl HOST LOSS RCVD SENT BEST AVG WORST er1.sfo1.speakeasy.net 0% 20 20 25.70 30.68 89.13 220.ge-0-1-0.cr2.sfo1.speakeasy.net 0% 20 20 24.02 26.56 58.23 ge-4-0-440.ipcolo1.SanJose1.Level3.net 0% 20 20 24.38 25.28 27.09 ae-1-56.bbr2.SanJose1.Level3.net 0% 20 20 24.26 31.00 97.58 so-3-0-0.mp1.SanFrancisco1.Level3.net 0% 20 20 25.49 28.89 49.58 so-10-0.ipcolo1.SanFranciso1.Level3.net 0% 20 20 25.17 25.81 26.73 gw-level3-sfo.internap.com 0% 20 20 27.32 28.12 29.58 border4.ge3-0-bbnet2.sfo.pnap.net 0% 20 20 27.11 28.24 28.93 ??? 100% 0 20 0.00 0.00 0.00 If you can figure out how to make sense of this, you might be able to find the point that a system is connected to the internet, by tracing back to a visitors current IP address. If you come up with something useful, keep the list informed.
