Xip.io – wildcard DNS for everyone
xip.io
xip.io
but the front page is cached at http://webcache.googleusercontent.com/search?q=cache:o8L_uDk...
with google site:xip.io you can see that this is mostly used to point at super-dodgy looking content (using an alternate "base36" representation of IP addresses) so that's awful
example.9zlhb.xip.io has address 127.0.0.1
