netbuzz writes "From this week's IETF meeting in Anaheim comes word that leading Web content providers are talking about creating a shared list of customers who can access their Web sites via IPv6. The DNS Whitelist for IPv6 would be used to serve content to these IP addresses via IPv6 rather than through IPv4. David Temkin, network engineering manager with Netflix, says: 'We're looking into the same service that Google has, where we will try to track what connectivity the user has. We're in discussions with Google, Yahoo, Netflix and Microsoft to see whether it makes sense to have a shared, open source DNS whitelist service.' ISPs are not wild about the idea."
