I'm quite confused why this is getting attention. It's not hugely difficult to enable a public IPv6 address on a server alongside the IPv4 address. The advantage of doing so? If one runs a serious website, there are many more back-end servers that handle database requests etc. than there are user-facing webservers, and all of these back-end servers can use IPv6 to talk to each other and the webservers. If IPv6 addresses are cheaper and easier to get, then it's a win for the company. They can upgrade each internal client-server pair to IPv6 in unison since they're a single organization.
