Sounds like "no one knows yet, so lets not shoot ourselves in the foot by underallocating prematurely"
Would it make more sense to allocate a smaller chunk, but sparsely? If it turns out the smaller chunk suffices (e.g. a /60* is more than almost anyone needs), then the remaing 15 /60s** can be allocated to other users, but if everyone really needs a /56, the existing allocations can be bumped up in place (no renumbering, just access to a larger block.) Or is 64 bits so huge that the mind can't cope and everyone really does need a /48 for home use and this won't force IPv7(?) with 512-bit addresses before anyone suspects? Does every proton in the universe need its own subnet? * or a /56 or whatever ** or the remaining 254 /56's as the case may be On Thu, 13 Aug 2015, David Huberman wrote: > ARIN does sparse allocation, where every /32 has 15 more /32s reserved for > you (a /28).
