The prevailing assumption is that IPv6 end nodes will be globally addressable for practical purporses. I think this is a very unlikely outcome. Section 4 in the draft may be common knowledge, but often deliberately ignored during protocol design because "it's not the way the Internet works" (or some other reason remotely derived from rather general policies). (BTW, the draft should be a bit clearer about the new waist's properties -- only very specific traffic patterns are widely NAT-compatible.) _______________________________________________ Ietf@xxxxxxxx http://www.ietf.org/mailman/listinfo/ietf
