Our external IPv6 web accesses are still very low, but have grown
linearly over the last five years from 0.1% in 2005/06 to 0.5% of
total web traffic now.   Internally of course our figures are higher.

Of that IPv6 traffic, 1% comes from 2002::/16 prefixes.   Even less
from Teredo prefixes.   I guess we could run stats against known TB
prefixes to determine who is using those.
