I see numerous statistics from Google and similar sources that indicate the percentage of end users who are IPv6 native. What I'm missing are statistics going the other way - what percentage of sites (or endpoints that customers regularly connect to) are IPv6-native, from a total traffic perspective? That is, if I switch to IPv6 on my eyeball network, how much of my existing traffic will I have to CGNAT in some way to reach the IPv4-only network? We have sufficient IPv4 address resources to stick with IPv4 for the foreseeable future. However, at some point, the percentage of traffic using IPv6 becomes so high that the reasons not to move become less significant. For example, the CGNAT box becomes significantly smaller, as most of the traffic should flow around it on IPv6. -- - Forrest
