Happy IPv6 day

Are you ready for IPv6 Day?

Google has a handy little test to see if you are going to have any issues with the cut over.

For those of you that don't know about it, IPv6 day is the 24 hour test run for GoogleFacebookYahoo!Akamai and Limelight Networks and some of the major organizations that will offer their content over IPv6 for a 24-hour test period. The goal of the Test Day is to motivate organizations across the industry – ISPs, hardware makers, operating system vendors and web companies – to prepare their services for IPv6 to ensure a successful transition as IPv4 addresses run out.

You can read more about it on World IPv6 Day.


  1. seems to be working ok so far.

  2. Really, how soon is it that IPv4 addresses run out? My ISP is still IPv4 but they are a small local company and my only other option is the devils at AT&T or Comcast.

  3. @Quinn, as far as I know the last block of IPv4 addresses was already allocated. All that means is that they have been divided up to organizations for use, many ISP's have thousands of IP's in their assigned block and utilize them as needed. I don't think that we are in any danger of "running out" and having a crisis. Your ISP will likely deal with the IPv6 translation at their router. Eventually I believe that you will need to deal with it by buying new hardware (for your router) but I imagine home users will never know the difference. For ISP, and backbone providers that have to implement BGP I imagine this was a serious headache.
