Sure, however as we saw with RFID tags, there were/are equally good reasons why people/companies don’t want globally (presumably unmodifiable) unique IDs. > With secure routing like RPKI, only the company produce that medicine can > announce that IPv6 address and returns the correct information. This implies that the individual IPv6 addresses would be routable down to a /128. How will that work? Regards, -drc
