IPv6 Fails to Penetrate Internet
Maxwell Cooter writes on TechWorld:
Only a small percentage of the Internet supports the emerging protocol IPv6 despite the technology being mandated [.pdf] by the US government.More here.
Figures from the web monitoring company Pingdom showed that just four percent of the Internet supports IPv6. Furthermore, an examination of the traffic at the Internet's biggest exchange AMS-IX showed that just 0.25 percent of Internet traffic is IPv6 and that the world is expected to run out of IP addresses by 2012. Pingdom doesn't pull punches on this, describing the situation as a "crisis".
That's not something that Internet numbering authority ICANN will go along with, "I don't think that a word like "crisis" is a helpful way to characterise the situation. Clearly, a lot of people need to do a lot of work but the work that needs to be done is achievable and in many cases has already started," said Leo Vegoda number resources manager at ICANN's IP address adjunct IANA.
Of course, It wasn't supposed to be like this: Pingdom showed a slide from a Cisco presentation from 2002 which suggested that IPv6 would be fully adopted by 2007. "Generally speaking, if you look at the current state of things, adoption will have to be sped up significantly over the coming 2-3 years. At the current rate, we'll have IPv6 fully deployed a decade or so later than when we need it, said a Pingdom spokesman.
