Vint Cerf wants YOU to use IPv6

The IPv6 Transition

What is IPv6?
IPv6 is the next generation of the Internet Protocol, which is the language used by computers and other devices to communicate on the Internet. The current version, IPv4, only has enough addresses for 4 billion devices, and these addresses are being depleted quickly. By moving to IPv6, it will be possible for around 2128 (approx. 3.4 x 1034) devices to join the Internet.

Is the transition actually happening?
Yes! The Internet standards committees, all large Internet providers, and major organizations such as Google, Facebook, and many governments are all committed to IPv6 migration. Wikipedia has a nice round-up with more information: IPv6 Deployment.

How much time is left?
IPv4 addresses are assigned in a hierarchical fashion, first as large blocks by ICANN and then in smaller blocks by Regional Internet Registries such as ARIN and RIPE. The number of blocks still available for assignment by ICANN is currently in the single digits (Dec. 2010). For further discussion, see Geoff Huston's IPv4 Address Report and Hurricane Electric's IPv4 Exhaustian Counters.

Why did you make this?

Why doesn't this website use IPv6?
I know -- sorry. I'm currently working with the campus' network staff on other projects more closely related to my research, but advocating for IPv6 connectivity is next!
