Re: Vehicle's VIN in IPv6.

[Thierry Ernst <[e-mail]>]

Dear all,

I fail to see why a VIN would be mapped to an IPv6 address as much as I 
fail to see why a passport number would be mapped to an IPv6 number. As 
said by Scott, the purpose of the IP address is to forward packets to 
the destination.

Such an idea is going against location privacy. To address the location 
privacy issue related to the ID of the vehicle used at the networking 
layer, the Car-to-Car Communication Consortium propose to use 
pseudonyms; when it goes to IPv6 communications (all communications are 
not IP-based) this pseudonym is used to configure an IPv6 address, i.e. 
a transient address (you can check the work of the SeVeCom project). In 
the meantime, the vehicle also has a permanent address (indeed, prefix) 
as which the vehicle is reachable (using NEMO). Up to now, there is no 
one in any of the standardisation or consortium I know (ETSI TC ITS, ISO 
TC204, ISO TC22, CEN TC278, Car2Car Communication Consortium) who is 
thinking about mapping a vehicle ID to the IPv6 address.

So, I'm afraid this idea is going nowhere.

Regards,
Thierry Ernst.
