With the increasing IPv6 deployment the concerns about potential privacy problems re-surface again. In the presentation we tried to highlight two aspects:
- It is very important to describe the threat model (and there are various aspects one can be worried about).
- The focus on the MAC-generated IPv6 interface identifier is not the only aspect to look at when dealing with address privacy. The question of IPv6 privacy is more complicated.
I often hear IPv6 privacy concerns in Internet governance meetings and I wish that the discussions could be a bit more focused.
To provide some data about what is implemented and deployed we suggest to start a survey. The current survey proposal writeup is available here:
(It has not yet been distributed yet.)
