The original draft talked about two modes, authenticated and non

This was not a perfect terminology, and we now use registered vs non

Question: in the non-registered mode is there an ability to have a mechanism
by which the same host gets the same IPv6 address each time it sets up
a tunnel?

Not today. Do you want to require such a mechanism?


- The registered part of the protocol SHOULD not be too different from
the non registered one,
so as to minimize code difference between the two modes

Are we assuming that the registration is done as part of the protocol
itself, or are we assuming that the registration is external to the protocol?

unspecified at this time.

In the latter case you can the ISP that supports registered tunnels can
have a web site where the user types in the credentials it uses
with the ISP (userid? contract number? whatever)
and as a result gets some registration key/tag which will be used
in the actual tunnel setup protocol.

That is definitively one way of doing it.

This could be a way to unify the two modes: if you are unregistered,
you provide an empty key and the system could (if desired by the ISP)
allocate you one so you would be able to retrieve the same address next time
by presenting that key.

In the registered mode, you provide the key that was pre-assigned to you.

Question: are we not already in solution space?
