There has been a lot of misinformation concerning the use of JavaScript in obtaining the real IP address of a user visiting a web page through an anonymous proxy (or proxies).
I'm not talking about Java, ActiveX, Flash, VBSscript,perl.

The question is about clients that ONLY have JavaScript enabled in their browser.

Of course I dont think it's possible, in fact this is what I found:

JavaScript itself has no way of reading the IP address of the local computer and so for JavaScript to obtain that information we need to use a different language to obtain the information. Once possible way of doing this is to call Java to get the information for you.

Anyone can confirm it?

You would have to place the page on a server that supports SSI, then set it up to parse the HTML page for SSI directives, there's no real way to do it without server side scripting on a static page.

Using javascript, a site can get an educated guess as to the fact that you are using a proxy or not.

Using javascript alone, they can not read your "internet" ip. Using javascript alone, the can get your private ip (192.x.x.x/10.x.x.x) if you are behind a NAT.

It's impossible. The only way is SSI

Just tested the SSI, you cant get the IP if the user is using a socksfier.
You can test it here: http://www.javascriptkit.com/howto/ssi3.shtml
