Dear all

The update covers a flow that was discussed at 6lo during IETF 118 and 
that relates to the prefix delegation work at v6Ops. The flow was added 
where the address or prefix that is registered was obtained with DHCP.

In that case, the recommendation is to use the ROVR (RFC 8928) as DHCP 
DUID. The ROVR is a crypto token that is associated with the registered 
resource and can be validated later.

This way, the router can use a lease query to (and the RFC 8928 proof of 
ownership) to validate that the address or prefix was indeed delegated 
to the node that performs the registration.

all the best;

> Abstract:
>     This document presents an architecture for IPv6 access networks that
>     decouples the network-layer concepts of Links, Interface, and Subnets
>     from the link-layer concepts of links, ports, and broadcast domains,
>     and limits the reliance on link-layer broadcasts.  This architecture
>     is suitable for IPv6 over any network, including non-broadcast
>     networks, which is typically the case for intangible media such as
>     wireless and overlays.  A study of the issues with IPv6 ND over
>     intangible media is presented, and a framework to solve those issues
>     within the new architecture is proposed.
