The fact that only 1/8th is assigned to "the Internet" right now is worrying. After all, we know how that worked out with the 240.0.0.0/4 range in IPv4 - it was reserved for future use, but was never able to be used because by the time it would have been useful, everything classed it as non-routable. It's a huge swath of addresses that just can't be used.
- dspillett 11y agoThe only solution to that sort of thing is just to be bloody minded. Make it known from the start that when the currently unallocated blocks are needed they will be used, and if that breaks things for people who have used them already that is their fault and their problem to fix.
- Sophira 11y agoTo be clear, I don't mean that 240.0.0.0/4 isn't able to be globally routable because everybody's using it for their own private stuff. I mean that 240.0.0.0/4 isn't routable at all.
- msbarnett 11y agoEven if everything and everyone fails to learn the lesson of 240.0.0.0, and ignores the standard, and hard-codes the assumption that 7/8's of IPv6 is unusable forevermore, 1/8 of 340 trillion trillion trillion is still unfathomably huge
