SLAAC with prefixes of arbitrary length in PIO (Variable SLAAC) - A
Problem Statement
draft-mishra-v6ops-variable-slaac-problem-stmt-01
Abstract
In the past, various IPv6 addressing models have been proposed based
on a subnet hierarchy embedding a 64-bit prefix. The last remnant of
IPv6 classful addressing is a inflexible interface identifier
boundary at /64. This document details the 64-bit boundary problem
statement.

14 [RFC2119] [RFC8174] when, and only when, they appear in all
capitals, as shown here.
2. Introduction
From the beginning, the IPv6 addressing plan was based on a 128 bit
address format made up of 8 hextets which were broken down into a 64
bit four hextet prefix and 64 bit four hextet interface identifier.
