It is not necessary to explicitly embed the code into the page. The
trade-off is having to use unsafeWindow. The following works for me.
var ip = unsafeWindow.java.net.Socket(document.location.host,
document.location.port || 80)
.getLocalAddress().getHostAddress();
alert(ip);
I found that Socket must be passed the host and port of the window the
scripts runs on, otherwise the browser triggers a security exception.
