I wrote a blog on my work website about IPv6 because I kept meeting customers with no clue about IPv6 but were worried about the hype.
Now that those in the know seem to have more of an act together, we are about to hit a different hurdle.
Most of the big networks (including mine) run dual-stack. This means any devices that need to see the “v6 Internet” are given an IPv6 address. There is nothing in the network for traditional IPv4 devices to see this new world, mainly because there are lots of approaches and no common standard. To be honest though, dual-stack is simplest to implement, understand and use.
The avaerage home broadband user on the other hand has an IPv4 address, behind a router that probably only does IPv4 into a network that most likley has IPv6 hidden in a corner. It is when these guys start feeling the pinch about address space that things will step-change.
There will be a land-grab for IPv4 addresses in the meantime as changing to IPv6 costs money. Keeping IPv4 doesn’t. Except for buying up any available IPv4 assets. When those prices start getting silly, economic principles dictate that IPv6 takes over.
Until then, you can always see how ready you are for the new World: http://test-ipv6.com/
