No we *don't*. The IETF standards are decided by consensus, and the IID bits are not yours to play with for routing purposes. There are other legitimate uses for these 64 bits, such as embedding some crypto in the IID or privacy extensions.

Please, we are talking about point-to-point links here. Michel, what you say (and what is written in the draft) is perfectly reasonable, when thinking about a 'real' link. I think a PtP link is some kind of an exception. There is nothing 'inside' a PtP link, just a source and a destination. The only reason to use a subnet for such a link, is a better management. So why should a piece of software or a software developer rely on the fact, that there is a /64 on a PtP link. Again, it is correct to expect this from a usual link, but not from a PtP link. Maybe the ADDRARCH draft is flawed and it should clearly exclude PtP links when requiring a /64. So long, Christian
