We keep coming back to the same old problem and the same reasons we are going to hope it solves itself without having to change anything. 1) Its the wrong type of pain IPv4 exhaustion does cause problems, but not really enough problems or immediate enough problems to create an incentive to move away from the IPv4 Internet. It really does not matter very much to the typical Internet user if there are other people unable to join the party. It matters even less to them if those people are in far away countries. 2) NAT-NAT IPv4 still beats IPv6 Even with the restrictions of carrier NAT, most Internet users are going to prefer an Internet connection that gives access to the millions of IPv4 hosts than the hundreds of IPv6 hosts. This is an adoption trap. Nobody is going to move to IPv6 unless the functionality is superior to IPv4. Saying that IPv6 is X years behind is to miss the point. 3) There is no ask ISOC and others are very good at putting out these stories warning about the imminent IPv4 exhaustion. But this is wasted effort when the message reaches people who can do nothing in response. For a message to be effective, there has to be an ask, there has to be something concrete that the audience can do in response. As before I will suggest how I would address the issue: 1) Branding Every technology company that has wanted to establish an infrastructure to support their product has used branding as leverage. Remember 'Novell Ready', 'Entrust Ready', 'Windows Vista Ready'? We need an Internet Next Ready. And when consumers see that brand they need to know that what they are getting is going to work with the next generation Internet. Demanding 'Internet Next Ready' in new products, in Internet service is the ask. 2) Design for deployment People are not going to use IPv6 if it takes the slightest effort on their part. People are not going to switch their home networks over to IPv6 if it means a single device on the network is going to stop working. In my case it would cost me $4K to upgrade my 48" plotter to an IPv6 capable system. No way is that going to happen till there are $50 IPv6 plotters on EBay. I try to do as little management of my home network as possible. For the architecture to be acceptable it has to be totally transparent to me. Otherwise carrier grade NAT is going to be preferable as at least that is going to work. 3) Create incentives Even with branding, the incentives have to make sense. Merely having access to the IPv6 Internet available is not going to cause people to use it. Pretty much every host on the Internet can use IPSEC at this point. The portion that use it is ~ 0%. The way that I plot out a campaign is to list every stakeholder that I need to take action. I consider the positive/negative balance sheet from their point of view. I look at the incentive they have to take action and how they are to get the message that they need to take action. Now I can draft out an architecture that would have the necessary properties quite easily. And so could many others on this list. But that would be a mistake. In order to get buy in from all the people whose buy in is needed, they have to be involved at the design stage. Having the had the opportunity to be involved is not the same thing. _______________________________________________ Ietf mailing list Ietf@xxxxxxxx https://www.ietf.org/mailman/listinfo/ietf
