Re: An Internet IPv6 Transition Plan

I'm wondering if we should really be considering a "transition" plan at this point? From what I can see, there will be many IPv4 only networks around for many years to come. The technology doesn't have an expiration date. Rather than focusing on "transitioning" every network from v4 to v6, shouldn't this draft focus on how an "initial implementation of v6" is going to interop with v4 as we know it today? Personally, I see v6 as something that needed and desired by the certain groups. However, when looking at the enterprise, for example, better solutions are needed for things like multi-homing, last I checked. IPv4 will get more expensive as time goes on, but some will be willing to pay that price. Perhaps the biggest challenge, IMO, in this much more dynamic network, is DNS. How do I (or my new vendor) readdress every node at my site, and actually know what device has what address? rtadvd doesn't do DNS updates. DHCPv6 doesn't even hand out addresses. I've seen host-based approaches, is that the answer? How does all this happen securely? DNSSEC comes to mind, but that's a whole different story. Add, since a host can have many preferred addresses, which to use? How do deprecated addresses get withdrawn from DNS? I think a more successful approach would be to address how we plan to add v6 to the current network. Perhaps a transition plan is appropriate for some networks. But, I don't think this is a one-size fits all issue. This is the part that I have issue with: 2.3.4 Service Providers area MAY continue to offer IPv4-based Internet connectivity to their customers. Organizations MAY continue to use IPv4-based Internet connectivity. Organizations MAY remove IPv4-based Internet connectivity from Internet-facing servers. If I'm an IPv4 only site outside of this "perfect world", I just lost connectivity to parts those that moved to IPv6. Not everyone will follow this plan, and this will happen. For now, we need to learn how to co-exist. Thanks for your time, Chad
