It is awkward but not broken imho, so in this respect I would think twice changing RFC4291. However, I do agree Randy about magic bits and the pain involved. Actually, a lot IPv6 business recently has been around adding magic to IPv6 addressing, which I kind of find uncomfortable.. My personal take on this is that we keep things as they are now. It would be cool to have all IIDs as a binary blob but.. that does not give a reason to start changing the addressing architecture at this point. Brian's document could be a good place to hash out the "confusing" points of the magic bits - as a plain discussion document without a recommendation about next steps. - Jouni (hmm.. where this conservative me came from ;-) > > 2) We do maintenance of widely-implemented, widely-deployed protocols. > So I'm not sure why we should be scared about changing stuff in v6 > (particularly when we're still at a point in which the v6 traffic is > very small) > > 3) Whatever changes are needed should be done soon.
