I checked the top 1 million domains from Alexa by simply adding 
"www6.domain" to what Alexa lists.  From that, 745 (0.07%) have 
AAAA records.  Of those, 297 (39%) allowed me to successfully connect 
to TCP/80, 44 (5.91%) advertise loopback (::1), and 404 (54%) failed 
connections to TCP/80.  If one considers ::1 a failure, then 
404+44=448 (60%) are failures.
