+ - Ran out of ipv4 space! Time to break open the last E-class ipv4 range? 4 4

Submitted by deckardt

RFC3300 mentions another range consisting of about 268 million ipv4 addresses, all listed as "Reserved for Future Use". This 'magic' range is the E-class subnet of 240.0.0.0/4. What is keeping the ipv4 domain gods from releasing this range? It looks like 240/4 is blocked in a lot of code already. For example in Linux it is impossible to assign an address like 241.1.2.3/24 (try it and get greeted with a SIOCSIFADDR: Invalid argument). So now I ask you dear slashdot community, is it time to break open that last ~5% of ipv4 space? Now seems like the right time.

If you can't learn to do it well, learn to enjoy doing it badly.
