All, First, I would like ask people to move the ULA-C discussion off the IETF main list. We have a chartered working group (IPv6; to change to 6MAN in the next couple of days) that has an official work item to look at ULA-C. The best way to progress the topic is to participate that WG's effort. Here's the list: https://www1.ietf.org/mailman/listinfo/ipv6 Second, where are we with ULA-C? It should be obvious from this and other discussions that we are very far from consensus. But that does not mean that we are giving up on the task! I think most people agree that ULA-Cs have potentially very useful properties. The question is whether we can make them happen, and whether the advertised benefits can actually be realized. Here's the plan for moving forward: 1) Write a document about the benefits and difficulties relating to ULA-Cs. This helps us avoid repeating the same arguments in e-mail, and making it easier for us to decide what the right path forward is. 2) Write an updated/new proposed solution draft. The proponents of ULA-C are not happy with the current document, so a new one is needed. Again, its better to have something in writing so that we can all look at it. 3) Further discussion on the 6MAN list. Please make these steps happen. If you have cycles please volunteer to help with documents etc to the IPv6 chairs. I would also like to take the opportunity to state that we do need to be very careful about interpreting the opinion of the IETF. We should not and we do not "shoot ideas down" through the opinion of a few loud participants. But at the same time, if most of us think an idea is bad, the IETF needs to be able to say no. Finally, it is important to distinguish lack of interest and active opposition; generally we should allow consenting adults to do what they want, unless we believe the Internet will be hurt somehow by this.
