Google Apps would be IPv6 enabled from June 6

Google has announced that they are on schedule to enable IPv6 support on their Google Apps platform from June 6.

The company said:

Customers with SSO IP Whitelists and IPv6 capable equipment need to ensure that their SSO whitelist configuration contains their IPv6 network segments (if applicable).

Google tested this implementation for a day last year and it caused no disruption on their network.
