Hi,

This is interesting (technically out of scope for
"professionally managed" networks, perhaps).

Or a forged clone? If you are relying on the AR's IID
value for this, perhaps you need to specify that it must
be a pseudo-random value per RFC8064. Even so, there must
be a residual risk of a forgery.

You could use GRASP, but the AR is not a real registrar yet, so
IMHO it MUST NOT support the "AN_join_registrar" objective.
I think you'd need a short-lived "AN_adolescent_registrar"
objective, and you'd still need to check the link-local address,
so there would really be no advantage.

Presumably at this point it does support GRASP "AN_join_registrar"?
