How does http://to./ work?

"I believe that the way it works is simply who ever owns the TLD .to, simply set up an A record for the TLD itself and are providing this service.

For example, google.com and google.com. are actually the same address.

You can also access this site via http://to

Some domains use this technique to redirect you to where you can purchase domains from, this place seems to offer a free service."
