Weekend Project: Transition to IPv6

"Internet Protocol version 4 (IPv4) has certainly served the world well over the past few decades, but that's no reason to cling to it until the bitter end. You can start using its replacement IPv6 on your Linux machines and home network today.

"If you haven't worked with IPv6 before, you might have only heard one fact about it: that its expand, 128-bit address space is so much larger than IPv4's 32-bit space that it will never need to be expanded again. The curmudgeons may mutter, "never say never" at that claim, but it is true that the last unreserved IPv4 address blocks are predicted to be used up by September of 2011, at which point ISPs and businesses will be forced to start using IPv6 in order to roll out new networks.

"Still, if you are reading this Weekend Project, then you are connected to the Internet, so IPv4's address depletion hasn't hit you yet. But there is a lot more to IPv6 than just its large address space. IPv6 has built-in IPSec security features that are optional in IPv4 (and thus, rarely offered to consumers by ISPs), larger packet payloads called jumbograms that increase network efficiency, built-in support for mobile networking devices that move from one connection point to another as they travel, simplified routing and address autoconfiguration."
