Hi all,
The IETF has received a liaison statement from the ITU-T that their
Study Group SG20 is inviting inputs from the IETF regarding a work item
titled "Reference Model of IPv6 Addressing Plan for Internet of Things
Deployment? and the deadline for providing inputs is 2018/01/28. The
statement can be found at
https://datatracker.ietf.org/liaison/1546/
I have no further info and I am trying to get access to the referenced
documents. I just want to provide a heads up while that is in process.
Thanks
Suresh

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).
