There will always be a legacy tail. The dinosaurs can wallow in their swamp. Those who deploy v6 will benefit from it. Others will feel the heat of not moving; here in the UK it’s Sky and BT who have between them ~10M households on IPv6. That’s not failure. New communities will benefit. For example, the largest science experiments are now migrating to IPv6, e.g., CERN and WLCG is 70% there, SKA will use it. Tim
