Hi Fred, Thanks again. > > Question for you. What is the interaction with draft-gont-6man-deprecate- > eui64-based-addresses? In conversation with him there, you asked if he > would be folding your draft into his and therefore making yours redundant. > Does he plan to? If he does, it may be appropriate for you to become a co- > author on that paper. That conversation is nothing to do with Iid-lifetime draft which we submitted to v6ops. It is about ra-privacy which I submitted to 6man. Ra-privacy has been active for some months and the content of this new submitted draft, "deprecate EUI-64", is the same as some sections in ra-privacy. They wanted to have an informational draft recommending all operators to use stable addresses. Since I was improving ra-privacy, there was a discussion about this and since I had a section about "Not using EUI-64 in general" in my draft. I said it can be just changing a sentence in this section to recommend using stable addresses as a public address. I guessed we agreed on that. But now I see otherwise! Since they didn't discuss this with me and just suddenly submit a draft and used the content of ra-privacy, I just asked them whether they want to merge this work with their draft. But it appears they ignored my message! I thought in IETF you try first to improve the existing drafts and then if the existing draft does n't address what you plan to do, you would submit a new draft, but not copy and paste the content and make it new draft. > My sense, which could be completely incorrect, is that the exact value of the > IID isn't all that interesting to most operators, as once it is in use nobody > really cares how it was chosen.

Iid- Lifetime is not about how you generate IID. It doesn't matter for it. It only recommends a lifetime for the IID. You can use different approach to generate your IID but at the same time care about your privacy. Thanks again, -----------smile---------- Hosnieh . success is a journey, not a destination..
