Who Uses IPv6 Today?
I had planned to write a whole chapter on 6bone for IPv6 Essentials. (I do discuss 6bone in Chapter 1, “IPv6 Versus IPv4.”) The 6bone is a global IPv6 test network that was started in 1996, which today has more than 1,000 participating hosts. This shows that IPv6 is alive and can be used. Anyone interested can hook up to the 6bone and get started. When I started working on the 6bone chapter, I suddenly realized how many commercial and production networks already used IPv6: NTT Communications in Japan and Telia in Sweden, to name only two. I called some of the companies and talked to the managers of those IPv6 networks. And their baseline was: yes, there are a few things still missing, but we have what we need to get started and make it work. So this call goes out to all application developers: What the market needs is for you to port your applications to IPv6.
