Think he means his WAN or ISP IP address.

For example returning a users online / external ip address so that its location can be resolved in virtual earth etc.

Right. The external ip instead of the ip on a LAN.

Using InetAddress I can get the ip of the machine within its local area but I can't figure out a way to get the external ip.

Ah, that's actually harder than it sounds as you don't have access to the property in javascript and as we proxy cross domain requests if you did getText on something like whatismyip.org you would actually get the IP address of our proxy. However there is a way around this as we have a page that returns the IP address of the client. You can use the following code in a block or in advanced code to get access to this:
Code Snippet

var httpRequest = new window.XMLHttpRequest();
var url = "/Content/Components/Resources/WhatIsMyIP.aspx";
httpRequest.open("GET", url, false);
httpRequest.send(null)
var ip = httpRequest.responseText;

Excellent. Thanks! Just as soon as I get back to my machine I'll give it a try!

Thanks for the great solution!

I've been working on something very similar for my first block, but I had to do some bad workarounds because I was not aware that there was an aspx file on the Popfly server to get the "real" ip address.

I hope you guys don't mind if I built a simple block based on your code

That's fine we had put in their for this :-).

hostip.info have a nice web service which looks up address info based on IP address.
