Google is warning users of tomorrow’s test of IPv6, and more importantly of the fact that current IPv4 addresses have been depleted. I was only able to see the yellow banner in Linux running Firefox4, it never appeared on my Windows 7 machine.

While the banner is sure to cause some discussion among the non-networking crowd, I wish Google had included a link to more information. Instead they only include a link to test a users internet connection for IPv6 readiness. I don’t think the average user understands that their ISP is responsible for providing IPv6 connectivity, or of the problems that currently face IPv4.

I will give Google credit for starting the conversation. Hopefully, tomorrow there will be a lot of companies asking themselves what they must do to be ready for IPv6. Enterprise must lead IPv6 adoption, because as we all know, carriers are more than happy to sit on their butts as long as no one complains. The fact that so many ISP are considering CGN is a perfect example of that.
