Ask HN: Give me recommendations to improve jsonip.com

Hey folks. I wrote http://jsonip.com a while back and lots of folks seem to find it useful. So I'd like to ask for your tips on how it might be made better to be more useful for you.

As a quick primer, jsonip.com returns your ip as either a json object, or wrapped in a jsonp callback.

Usage:

http://jsonip.com => {"ip":"your ip"}

http://jsonip.com/cb/ => cb({"ip":"your ip"});

http://jsonip.com/randomgurgltyfurt/ => randomgurgltyfurt({"ip":"your ip"});
