Random point about this (my current employer is a national lab): In 2006, the OMB issued a requirement that new DoD/DoE/USG/etc IT spend ("to the maximum extent practicable") be IPv6-capable, and tasked NIST with developing a testing framework for determining compliance: http://www.whitehouse.gov/sites/default/files/omb/assets/omb/memoranda/fy2005/m05-22.pdf http://www.whitehouse.gov/sites/default/files/omb/assets/omb... http://management.energy.gov/documents/AttachmentFlash2010-48.pdf http://management.energy.gov/documents/AttachmentFlash2010-4... Mind you, we were also supposed to be running at least dual-stack by 2008. ;-) Anyway, as of the middle of last year, this came along: http://www.cio.gov/Documents/IPv6MemoFINAL.pdf http://www.cio.gov/Documents/IPv6MemoFINAL.pdf Basically, we have to be IPv6-capable on external services by 2012, and be ready for it enterprise-wide (for anything that touches the Internet; offline farms, etc. are exempt) by 2014. I don't suspect many organizations are going to hit that, but that's the target, and we're taking it pretty seriously here. Also, here's a random resource: a totally unofficial IPv6 survey: http://www.mrp.net/IPv6_Survey.html http://www.mrp.net/IPv6_Survey.html
