Hi - for a long time now, AERO has been advocating DHCPv6-PD for assigning
a /64 or shorter to a node that can act as either a host or a router. If a router,
the node assigns (portions of) the delegated prefix to one or more downstream
attached links. If a host, the node assigns (portions of) the delegated prefix to a
virtual interface and configures as many addresses from the prefix as it likes on
the virtual interface. The node can then enable host applications that use the
assigned addresses according to the weak end system model. I suppose it is
also possible for the node to act as both a host and a router, if such would
be required according to the use case.

I also agree with what I think I heard Lorenzo saying at the mike, which is that
assigning a /64 or shorter to each node is scalable since even a /32 can support
up to 4B such nodes. That is also consistent with what AERO expects.

Here is a pointer to the AERO draft:

Thanks in advance for any comments.
