Apparently, my point was not very reader friendly, so I'll try again: Routing-wise, someone with 64 billion billion billion addresses, have about 16 billion billion ways to route the entire IPv4 internet, within the address space constraints of a /32 allocation. Even if we pretend that it's an extremely useful and necessary thing to have a /64 per end user, so that each end user can enumerate and route the entire EUI-64 space, a /32 is still the same as the entire IPv4 space. That there is a "need" for allocating as much as a /32 in the first place is a design failure in how the addressing segmentation has been handled, in my opinion. It's the IPv4 /8 allocation mistake all over again. Also, as I said, and obviously have to repeat for some people: that cat is out of the bag. It is what it is. But there is no need to compound this design failure. -- Jan -------------- next part -------------- An HTML attachment was scrubbed...
