Quick Proxy question

I found a list of working proxies. Now when I go to whatismyipaddress it shows a message that "Proxy Server Detected" and shows the IP of the proxy.

Under that it shows "Proxy Reports IP as: xx.xxx.xx.xxx" which is my ISP's IP.

Does this mean that the proxy leaks the IP? I'm guessing Google and Yahoo will see my IP rather than the proxy's IP. Am I right?

Thanks for the help guys

Yep. Get better proxies.

Well often not-anonymous proxies are not valued enough or thrown away too fast.

Your proxy is leaking your IP and the fact you are using a proxy in the HTTP headers, that's data that is send with every request and it contains stuff like variables you entered, browser settings, languages you prefer and similar information.
Your proxy adds a few lines.

This means your real IP is not protected but a website has to look for this information to be able to see your real IP. The default approach is to look for the IP that is connecting and that will be the proxy IP.

So depending on what you are going to do it might still be possible your proxy is ok for the job.
