That reminds me of: "640K ought te be enough for everyone".

That was DOS think. We got rid of that. Now 640M is meagre.

We also have to get rid of IPv4 think. On top of that list are:

1) NAT is not a security feature.
2) There is no shortage of addresses. Address space is no longer a scarce commodity.

With the mind still in IPv4 think mode, giving out a /56 to everyone while the vast majority will get no further than using 1 or 2% of that looks like a terrible waste.

Then consider that "waste" is only an issue if there is shortage. With IPv6 there is no shortage of addreses. Thinking "waste" is IPv4 think. We have to get rid of that.


Cheers, Michiel
