IPv6

["Irwin Lazar" <ILazar () burtongroup com>]

Excuse the off-topic question, but does anyone know if there is some sort of list anywhere of service providers who are 
running IPv6 in a production capacity, either to tunnel IPv4 or to offer native IPv6 services?  I'm not looking for 
test or research networks but rather a list of IPv6 networks that are actually carrying customer traffic.
 
Thanks,
Irwin
