Hmm. I'm afraid that I have to disagree with just about everything you've said :) . I haven't seen any enterprise folks demanding v6 - If VOIP and PDA's (?) use up their IP addresses, they can easily ask for more. The more you use, the more you get. There is no shortage of v4 space. China and Japan are not mandating anything, AFAIK. I believe that v6 deployment is being encouraged by some countries, and the spread of 3G is helping things along, but we have yet to see really widespread v6 deployments anywhere. Basically, major backbone networks will deploy v6 when it makes economic sense for them to do so. Right now, there is no demand and no revenue upside. I don't expect this to change in the near future. v6 is, currently, a solution in search of a problem. v4 space is being consumed slowly, but we are quite some time from a crisis. Of course, even when we "consume" all such ipv4 space, there are still expedients that can be used, including making v4 assets tradable and fungible. - Dan Irwin Lazar Said...
Since we're on the topic of IPv6, I wanted to gauge the current attitude of the ops. community toward its deployment. We're seeing a lot more interest from our enterprise clients in using v6, especially as things like VoIP and PDAs consume their address pools, and NAT gets in the way of collaborative apps such as netmeeting and business-to-business connectivity. However, the road-block seems to be the lack of ISPs that offer IPv6 services.
Given that places like China & Japan are now mandating IPv6 for their ISPs, does anyone see anything resembling a growing momentum toward IPv6 adoption, or is it still a moot issue for you guys?
