Why can't the people who want to use IPv4 use that and the people who want to use IPv6 use that. If IP and appletalk can survive in the same network then IPv4 should be able to survive with IPv6. Sounds to me as if what is really being proposed here is to shut down the IPv4 connectivity. That will cause a serious loss of productivity for me. I am going to Chicago to work and not to participate in a LAN party or an interop. There are plenty of venues where that can take place. With 1200 attendees paying $600 plus travel to attend the meeting is costing well over a million dollars. I agree that we should do dog food. The fact that this experiment cannot take place is the data point. People have to accept the data point and think through the deployment strategy more thoroughly. Back when laptops first came out you have to buy one power brick for the US and a second one for Europe. The modern multi-voltage power supply only appeared when an Apple vice president got angry when he discovered he dd not have the right adaptor, returned to the engineering dept and told them that from now on the machine would work on any mains electricity anywhere in the world. > -----Original Message----- > From: Thierry Ernst [mailto:thierry.ernst@xxxxxxxx] > Sent: Tuesday, July 03, 2007 4:05 AM > To: ietf@xxxxxxxx > Subject: Re: chicago IETF IPv6 connectivity > > > Did we forget the IETF motto about running code ? > > I do understand that there is a need to alleviate risks in > the operational network, so a traditional operational IPv4 > network has to be maintained until a vast majority of IETFers > have assessed the proper operation of IPv6. > > But this doesn't prevent to operate a more advanced > technology simultaneously.
