When you read draft-despres-6rd-02, you will see that Free, the second largest ISP in France, with millions os DSL customers, deployed 6rd in 5 weeks (6rd stands for IPv6 Rapid Deployment.)Mohacsi Janos wrote:On Thu, 26 Mar 2009, Mark Smith wrote:I agree with Remi, 6RD isn't a functionally equivalent alternative to 6to4.The most important difference is that 6RD forcing to the provider to provision their own relay.Except that it doesn't.This is a little bit of semantics on the surface, but there's a very real point behind it.Many ISPs don't care about supporting IPv6 yet. If you, as a customer, call their support line to task about it, you basically get something along the lines of, "What's IPv6? Have you rebooted your Windows and your (cable|DSL) modem?"If ISPs don't care enough to support, or even have an inkling of IPv6, they're also not going to deploy anything like 6RD (though I admit I'm just picking up on the 6RD conversation...but if it requires ISPs to deploy something, its basically dead in the water for a long time still).
The point is that ISPs, rather than setting up a 6to4 relay router should setup a 6rd Gateway in order to offer native IPv6 prefix to their customers.There are many people (myself included) that are happily using 6to4, and we're using 6to4 because the ISPs available to us are utterly and completely clueless, so we don't really have any other option. If the 6to4 anycast goes away and you require the ISP to deploy something for the replacement technology, you are effectively cutting us off from the IPv6 Internet for the foreseeable future.
The only other option I see is hard to manage and configure, and frequently bandwidth constrained, tunnel brokers.Taking them away is not needed. It's only that using them without precautions to reach native IPv6 servers will lead to customer frustration with, at least sometimes, poor quality IPv6 experience, something to be avoided.Oh, and my CPE supports 6to4, but not a tunnel broker sort of setup (at least that I can find...Apple Airport Extreme)I don't have any problem with 6RD as an additional transition mechanism...I'm not sure its worth the effort, but if people want to go down that path, then that's their choice...but please don't take away 6to4 anycast gateway or I, and several households that I work with, go away from the IPv6 Internet.
