Part of NTIA's mission is to convene stakeholders to address today's critical communications and technology issues. One of these issues is the adoption and deployment of Internet Protocol version six (IPv6).

Every device that connects to the Internet, such as computers, smartphones, and smart grids, require an IP address. IPv6 is an Internet addressing system designed to expand the number of IP addresses available because the current supply will eventually exhaust. The IPv6 transition is critical to the continued growth of the Internet. While industry action and planning are needed, consumers do not need to take action to prepare for the IPv6 transition.
