If it weren't for the stupidity of OS and IP stack authors, we'd be able to use the 240.0.0.0 - 255.255.255.254 addresses.
However, most of them refuse to route to those addresses because they're "Reserved for Future use."
Apparently no one stopped to think that blocking routing to those addresses would stop them from being used in the future because people insist on using older technology.
