Here are a few interesting takeaways:
1. Hewlett-Packard owns 33,554,432 Class A IPv4 addresses, or 1/128 of the IPv4 space -- apparently more than the countries of India and China combined (unverified).
2. The U.S. Department of Defense owns 150,994,944 IPv4 addresses. What the DoD is doing with almost 151 million IPv4 addresses is beyond me. I don't think anyone, or any country, in their right mind needs 150 million IPv4 addresses.
3. Massachusetts Institute of Technology owns 16,777,216 IPv4 addresses. No college needs almost 17 million IPv4 addresses for itself. According to Wikipedia, by comparison, some organizations such as Stanford University (formerly owner of the 36.0.0.0 - 36.255.255.255 range), have returned their designated ranges due to IP address shortages in recent years. Perhaps MIT should follow Stanford's lead?
4. The IANA has reserved approximately 251,658,240 IPv4 /8 addresses. I know some blocks are reserved for special use, but perhaps the IANA could release some of those blocks back to the world? We have a serious IPv4 shortage on our hands. Why is the IANA holding onto more than 250 million IPv4 addresses?

MIT wont give back their IP space they will simply sell it off to other colleges as needed. US government has a strict policy to move to IPv6 so this block could be getting returned. HP would never give back IP space because well they are in managed services as well and this is a valuable asset for them.
What needs to happen is APNIC needs to take back a bunch of IP space from china this would free up a TOOOON of space. But why would china want to do that and do the rest of the world a favor?
