Most people do, as long as they accept the spoon-feeding media model and stay away from potentially dangerous things like trying to challenge who gets to publicise things and whatnot. Anyway, there are other issues with non-unique addresses. Enterprises *WILL* use them, in large, expensive-to-renumber-since-we're-stupid-and-don't-use-DNS schemes. Enterprises merge. I'll gladly hand out the marshmallows to roast on the crash-and-burn fire when "unique behind my firewall" isn't. > If I understand correctly, ipv6 will force me into using provider > dependent globally unique address space. Yes, as long as you don't run a LIR. (One can argue whether this is The Way, I don't agree, but basically, this is what stands for now) > Unless my provider of the day is > required to assign me address space that is and/or permanently assigned > and portable it does not meet my needs. Why not? I am not willing to > renumber when I change providers. You are stuck in a v4 model. Renumbering is fun and healthy.

Your applications might have issues. Mine do, and I don't like them complaining.

There is an issue here -- various schemes have been presented (research ships, planes, anything) that are exotic at best, yet we can't completely ignore them. However, I do not think non-unique prefixen are the way to go. See above under "mergers". -- Måns Nilsson Systems Specialist +46 70 681 7204 KTHNOC MN1334-RIPE Attachment:
