It was just announced to day by Kundra, the new 'Federal CIO', that ALL Federal agencies have native IPv6 connectivity to public services, including Web, Email, DNS, and their Internet gateways. Equally interesting is the fact that the Federal agencies have 2 years to comply with the 'due date' of September 30, 2012.
Quite the game changer when it comes to IPv6 adoption, which has been painfully slow in the U.S. (non-North American areas are practically being forced to IPv6 because of the lack of IPv4 addresses for their country/region).
A very much needed push from the Federal government to get the commercial/private sector focused on the real business opportunities ahead for IPv6, and the real (and obvious to us network engineers) infrastructure upgrades that will be needed.
If you haven't been reading up on IPv6, now is certainly a good time.
