Dear all. For Internet connectivity of vehicles, the use of IPv6 (with mobility support, NEMO) is being fully considered at some standardization organizations such as ISO and ETSI. But, I totally disagree with the use of IPv6 as a permanent ID of a vehicle, i.e., VIN, because
1) This breaks the layered architecture concept. 2) This causes security issues, especially location privacy. For, the comments from Behcet, plz see inline.

The ITS station architecture being considered at ISO and ETSI defines that a vehicle ITS station must implement at least three entities such as the gateway, router, and host. The mobility support for Internet connectivity, i.e., NEMO, is in the router forming the in-vehicle network where hosts of the vehicle ITS station are attached. So, the use of link layer ID as the VIN does not make sense. In addition, the link layer ID for the router of vehicle is changed frequently, e.g., randomly generated ID is used for preventing location tracking. Even the security mechanism developed for securing the vehicle ITS station adopts an approach of pseudonym, i.e., certificate not including any identical information of vehicle and vehicle's owner and use in a given short time.
