What’s happening is the original
Internet numbering system — which assigns addresses such as 192.168.1.1 — is running out of numbers.
IPv4 is a
32-bit system with four billion possible combinations. “That sounds like a lot of numbers, but it really isn’t when you think about the size of the globe and the number of devices being connected these days,” Curran says. In fact, we’re due to run out of numbers within 700 days, he warns.
IPv6, with
128-bit addressing space, enables “numbering of all of the molecules in the galaxy,” he says.
As soon as the last IPv4 number is used up, every new device or site that comes along after that uses IPv6. Don’t loose too much sleep over your systems, however. Industry planners have been aware of this matter since the
1990s. Most
hardware and
software has been ready for IPv6 for some time.

An important task that everyone needs to do is make sure that all public web sites get add IPv6 connectivity as soon as possible. This will insure that these web sites are directly reachable to new customers connecting via IPv6...
Google's announced their plans, http://www.google.com/intl/en/ipv6/, so your blog here is probably fine, but you should inquire about IPv6 from any other websites that you're counting on.
