So I guess today is the launch (or at least attempted launch) of support for IPv6 across all ISPs by Google and others. 

There is an nice little infographic and video found here to help out if it doesn't make sense.

I'm kind of curious to find out where this goes. Working a bit with networking myself, I am a bit familiar with IPv6, but I know that it is very foreign to a lot of computer geeks out there, and I know I don't know it nearly as well as I should if they are really trying to launch this globally. 

I guess for me, part of what makes the transition so difficult is the fact that IPv4 is in decimal (well, at least translated to decimal) and makes it easy to remember, while IPv6 is in hexadecimal, and much more of a challenge to remember unique addresses. The transition seems to be a bit similar to the attempts to change the US to the metric system. Just not sure how effective it will be. 

What are your thoughts on this transition? Does IPv6 make sense for you? Do you see it being used globally? And if so, how long would the transition actually take?
