wildcard dns for everyone xip.io

Interesting...

What is xip.io?
xip.io is a magic domain name that provides wildcard DNS
for any IP address. Say your LAN IP address is 10.0.0.1.
Using xip.io,

          10.0.0.1.xip.io   resolves to   10.0.0.1
      www.10.0.0.1.xip.io   resolves to   10.0.0.1
   mysite.10.0.0.1.xip.io   resolves to   10.0.0.1
  foo.bar.10.0.0.1.xip.io   resolves to   10.0.0.1

...and so on. You can use these domains to access virtual
hosts on your development web server from devices on your
local network, like iPads, iPhones, and other computers.
No configuration required!

Think about what can it do for you?
