But i guess if you are beind a router you don't need to worry about it as the router blobks of you LAN ip address and surfs on the ip your isp assings you which is the WAN ip and that ip can be tracked by many means just go to sygate website try online scan and they will get you WAN ip but not your LAN ip.I guess even if you use a proxy your wan ip can be tracked as we can't do anything about that as that is on the isp side
