Re: [Int-dir] Liaison statement received from ITU-T regarding a "Reference Model of IPv6 Addressing Plan for Internet of Things Deployment"

Thanks. I would like to also get operational commentary from v6ops. Like you, when I search for the document, I come up to a paywall; the document is not openly available. Please forward either the document or the link when ITU decides to get serious about asking for comment.

A general comment: the model being followed in RFC 4861 and in the various IOT groups is fundamentally as follows. The IPv6 address consists of a prefix and an IID. In the general Internet, routing operates on prefixes, and a subnet is identified by a prefix. Within a subnet defined by WiFi, Bluetooth, IEEE 802.15.4/4g, Power Line Communication technologies, and the like, network elements generally use some form of host routing, whether source or distributed, on the presumption that topologies may be continuously changing or devices may be moving. 6LowPAN specifically has some recommendations on the structure of the address designed to minimize the actual size of an IPv6 header, and in many of them, that is treated as a lower layer problem. I'd like to believe that the work party is sufficiently clued in to not want to materially change that without discussing it with us (putting documents behind a paywall not being a great example of open discussion).
