More than 20 years into its transition, IPv6 adoption still not gathering enough momentum to overtake IPv4 as the Internet protocol standard.

In his talk on global adoption of IPv6, organized by the Internet Governance Project, Alain Durand, Principal Technologist at ICANN, notes that more than 20 years into its transition, IPv6 is still not being adopted globally at a sufficient rate to prevent fragmentation and promote Internet stability.

In some countries, like the U.S. and India, IPv6 adoption is making good progress.  However, in others, where incentives to migrate are low, IPv6 still is non-existent or stagnating at low adoption levels, and it may be time to consider a new approach.
