No IPv6
I did a search of the document for IPv6 and didn't find anything of it, yet it is one of the things that has been touted to increase traceability, if not security per-se eg. Belgium's insistence on reducing CGNat to 16 per IP which then drove faster IPv6 adoption.
I'd really love to know to what extent IPv6 is already being used and whether the trigger will ever be pulled on the death of IPv4. The whole subject just seems to be a bit of a black hole.
