One of the very useful things we can do with BIG-IP is present both IPV4 and/or IPV6 addresses to the outside world. On the inside, devices can be a mix of V4 and V6. That really helps simplify migration issues when someone wants to move to IPV6. Japan has been leading the charge in the migration but it is picking up in other parts of Asia as well.

One of my colleagues sent this Computerworld Australia article along that talks about why IPV6 is "a pie to be consumed here and now".
