Re: Vehicle's VIN in IPv6.

There is a general model here which will re-occur many many times.

manufacturers have context-specific serial numbers which behave in context like EUI164.

It is reasonable (from their perspective) to ask if there is an address management function which can suit their context, to exploit IPv6. Perhaps a private overlay network for IPSEC trusted remote upload and download. re-blow your SONY TV on any Internet via a trust path homed inside the manufacturer. 'ET call home' models of device management.

I believe we have to have this discussion, but can I point out that global address policy lies in many places, only some of which are held in IETF Mailing lists.

So, a decision to establish a registry which spans outside of the private domain, and touches into global-unicast behaviours really has to be far, far wider than 'here'

It has to encompass the RIR process, basically. Or, clarify why its not in that model/space.

128 bits is a higher trust. we have to run this in the wider public interest. We currently hold ourselves to a tiny footprint for a reason, but that reason doesn't EXCLUDE this discussion, it certainly informs it.
