Who took control of the Pentagon's IP space and why?

A company called Global Resource Systems came out of nowhere and started announcing that it had control over a huge portion of internet real estate that used to belong to the Pentagon. This internet space is called IPV4, and it's crucial to how traffic is routed around the world. Now this portion of space that belonged to the Pentagon has never been active before. It's sort of like land that's not developed. There's no roads to it. Nothing is built on it. Nobody goes there. But with Global Resource Systems - we'll call them GRS - making this announcement, that suddenly changed very quickly. Suddenly there's a ton of traffic going to this block of IPV4 space.  So many questions abound. Why did the Pentagon give control over this space to an unknown company? What does it mean that it now controls so much IP space? Should organizations that are navigating the internet be worried about this? To help me sort it all out, we have a special guest on the podcast today. Mark Jeftovic is the CEO of EasyDNS. He's also a member of the Canada chapter for the Internet Society.
