Just update for those that care. As you may know, all the major cellular providers in the USA (VZ, AT&T, T-Mobile, Sprint) support IPv6 by default on many models of phones. Comcast and AT&T and other large broadband players also have IPv6 widely deployed by default http://www.worldipv6launch.org/measurements/ Most of the major (elephants) content is IPv6 (Google, FB, Netflix, ...) And now the other end in the cloud is coming along nicely https://aws.amazon.com/blogs/aws/aws-ipv6-update-global-support-spanning-15-... https://docs.microsoft.com/en-us/azure/load-balancer/load-balancer-ipv6-over... https://cloud.google.com/compute/docs/load-balancing/ipv6 Not to mention that Digital Ocean , Softlayer / IBM, Linode, and others also support IPv6 And now you are seeing ipv4 lose support in various classes of products like set-top boxes ( http://corporate.comcast.com/comcast-voices/world-ipv6-launch-four-years-lat... ) and static IPs ( https://www.theregister.co.uk/2017/03/10/verizon_running_out_of_ipv4_address... )
