Firefox 跟 Chrome支持WebRTC可以向STUN服务器请求，返回内外网IP，不同于XMLHttpRequest请求，STUN请求开发者工具当中看不到网络请求的。

            This demo secretly makes requests to STUN servers that can log your
            request. These requests do not show up in developer consoles and
            cannot be blocked by browser plugins (AdBlock, Ghostery, etc.).

不管你经过了多少次代理，不管你网络情况是如何的复杂，都能获取到你真实的出口IP地址的。只支持chrome和Firefox浏览器。
