In the conclusion to that 2002 article, djb writes: ---- The way to make IPv6 addresses work is to teach every Internet computer how to talk to IPv6 addresses---not just as an option that the sysadmin might configure, but as something that's automatically enabled as part of regular software/hardware upgrades. ---- Today, most all operating system do speak IPv6 - and in many cases it is enabled by default. And there are plenty of IPv6-to-IPv4 gateways and other technologies so that you can, in fact, have an IPv6 network with access to IPv4 resources. We've come a LONG way. We still have a good way to go, but we're in a much better place than we were 10 years ago.
