If you are using Google Apps for your business or organization, you’ll want to be aware that Google is enabling a new addressing structure called IPV6 [wiki] on their websites tomorrow, Wednesday, June 8. There is some potential for problems, but most people will be okay. Below is the message I received from Google. I’ve added bold to one particular sentence that allows you to test your system now.

Dear Google Apps administrator,

On June 8th, 2011 — World IPv6 Day (http://worldipv6day.org/) — major web companies, including Google, Facebook, Yahoo!, and Microsoft, will enable IPv6 on many of their websites for 24 hours to test how IPv6 performs in the real world.  That day, we’ll be using IPv6 (http://worldipv6day.org/faq/index.html) for Google Apps, including Gmail, Google Calendar, Google Docs and Google Sites.

More than 99.9% of people shouldn’t have any problems during this industry-wide test, but your experience on June 8th will depend on your computer and network configuration.
- If you only have IPv4, you’ll simply use IPv4 as usual and not see any test-related problems.
- If your configuration is ready for IPv6, you’ll automatically use IPv6 and not see any test-related problems.
- In rare cases if you have IPv6 enabled but not configured properly, you may have connectivity issues with Google Apps and other test sites on June 8th.

If you’d like to start checking your organization’s IPv6 preparedness before June 8th, you can instruct your users to visitipv6test.google.com from the devices where they access Google Apps, like primary work machines, tablet devices and home computers. If you discover IPv6 connectivity problems, you can find troubleshooting tips and more information here:http://www.google.com/support/websearch/bin/answer.py?hl=en&topic=8995&answer=1299266

If you are having a major issue related to this from now until the end of June 8th, 2011 and need to contact us about IPv6, please submit your inquiry here: https://spreadsheets.google.com/a/google.com/spreadsheet/viewform?formkey=dGx2UnV1RTdEY25HSlJ4VGQ2QW9jM2c6MQ.  We will get back to you as soon as possible.

Thank you,
The Google Apps Team
