It's http://ipcalf.com!!!
I really have no idea either, but it's like the other animals only more minimal. IP Minanimal if you will, as a dot com.
Oh and also it does content negotiation!
Use it in shell scripts:
echo `curl -s http://ipcalf.com/?format=text`
Or in JavaScripts:
fermata.json("http://ipcalf.com/").get(function (e,d) { console.log("Yay pointless cross-origin request:", d); })
Or in LISP:
(ok (i dont actually know) lisp)
Go to net.ipcalf.com in a WebRTC-capable browser to see your local network IP address.
