But this is also AWS exerting price pressure on its customers. This move is an increase in price pressure, not a decrease. If everything host on AWS becomes dual stack and gets first class IPv6 support after this move, that's a win for IPv6. The price for v4 address is going to bob up and down as more networks and content providers adopt v6 and are able to reduce their public v4 usage to just their edges. There will definitely be a long tail of v4, especially in the corporate world, but I think we'll get to 90-95% v6 capable within the next 5-10 year
