There is just as big a block of addresses with class D addresses for 
broadcast. Is broadcast really even a thing these days? I know tons of 
work went into it, but it always seemed that brute force and ignorance 
won out using unicast. Even if it has some niche uses, I seriously doubt 
that it needs 400M addresses. If you wanted to reclaim ipv4 addresses it 
seems that class D and class E would be a much better target than loopback.

Mike, not that I have any stake in this
