Hi, As some others have also commented, I have serious concerns about the hain/templin draft.
An observation: This document seems to take for granted that local-use addressing is needed. Moreover, it lists requirements for every possible case where local-use address could be applied to (and, not for example, those cases where the local-use addressing is really necessary). Process questions: 1. Shouldn't we first see the requirements for site-local replacement (and other issues) and not jump straight to the requirements for local addressing? 2. Then if we see that local addressing is required to do X, see that this document covers X adequately? 3. Not consider those not listed in the sum-of-all-X at all? (or at least, make the separation what scenarios require specific features clearer)? I don't send in more detailed comments on the draft, because I pretty much disagree with everything it says. If we explicitly make the decision that local-use addressing is needed in some scenarios, I might accept that and review it again with that in mind. Just two notes: 3.1 -- "Network managers have stated, and historical experience has shown, that there is a need for addresses that do not require public registration." ==> there is no supporting evidence of this expect vague statements. Please be more explicit as I don't see how we can take this for given. 3.2 "Applications require addresses that remain stable during intermittent connectivity, site mergers, ..." ==> it is not clear what you mean with stability, i.e. what the _real_ requirement is. Connection survibability, or something else?
