Hi, I basically agree with Jan.
I will say that the ITU friends contributing to this document need to come to the IETF and the RIR meetings to openly discuss and learn about the reality about operating IPv6 and IoT networks. In short the document makes no sense at all and is plenty of errors even in the way some notation, protocol names and references are used.

Dear RIPE Community and Document Proposer, First of all, for a full disclosure - I'm writing this review in my own personal capacity as a long time IPv6 advocate and member of the RIPE community. My views and comments do not necessarily represent the views of my employer. Reading through this document raised a few points in my minds, which are elaborated below: - Absence of problem statement. Technical documents normally identify the problem they're trying to address. Do we really have a problem, what is that problem, and what are we trying to solve? Is the addressing of IoT devices an actual issue anyone has? - No clear requirements If a problem is defined, what are the requirements for any solution? What is the scope of the document, and what is the framework under discussion. - Lack of documented operational experience or good practice What is the best current operational practice for this problem, or has an experimental environment involving many hundreds of devices identified a need for this solution? If neither is the case, what is the evidence that a prescribed solution with neither operational nor experimental experience would work as planned? - Factual errors There are several errors in the document, some of them were already pointed out and explained by Sander Steffann in his review. - Misunderstanding of how IPv6 addressing policy works A general reality is that network operators determine their IPv6 addressing plans depending on the type of network they are building and the purpose. Whilst it's possible to define certain best practices that can apply, these are invariably based on operational experience and are not prescriptive (i.e. 'bottom up' rather than 'top down'). IoT devices will be utilised in many different ways and in different types of networks, and whilst there may be merit in starting to think about IPv6 addressing plans for IoT, these should be formulated based on the collective experience of multiple diverse network operators. - What is the ITU's motivation for doing this? Internet standards were developed by organisations involved with its operation, and best practices evolved out of their direct operational experience. The network operator communities (e.g. RIPE) are therefore best placed to understand, define and implement IPv6 addressing plans for IoT devices. Other interested organisations including the ITU are of course encouraged to participate in this process, raise issues of concern to their communities, and contribute to the best current operational practice, but should not seek to prescribe solutions unilaterally. Personally, I feel the purpose of this proposal is unclear, and there is limited value in further discussion of this document for the various reasons described above. I would be open to review a future version of this document from SG20 that will take into account all the above concerns.
