3 Questions about Proxies\IPs: 1. I know that proxies such as ctunnel reroute your IP, successfully shown in IP testing sites, and I wanted to see if sites such as speedtest.net, with their locator that shows the closest port to you, if using a proxy would effectively get a speed testing site to think that I'm in another country or something, but it seems that java and flash, at least in certain cases, are disabled and I wondered why... 2. When it comes to tracking ip's, does a proxy provide a means to an end in regards to being the final destination for a tracking system, or can it extend past the proxy to find the original IP? 3. Is it possible to determine the originating IP address of an email sent to you?
