Surely the case is that you've still got the same number of users who need an IPv4 address to be able to access "legacy" IPv4 sites on the Internet - until 100% of content is accessible via IPv6. What it does, however, change is the amount of traffic which would need to flow through a CGN box. Unfortunately, CGN is here until either everything is available over IPv6, or a better version of NAT64 which doesn't depend on DNS rewriting is designed and deployed. Simon
