When RFC 6346 was published in 2011, the idea of addressing the IPv4 address exhaustion problem using Address+Port sharing was new and untried, and so it was published as experimental. In the intervening years, several mechanisms for deploying A+P have been documented and implemented, and are now seeing commercial deployment. Consequently, it seems appropriate to declare the A+P experiment a success. This proposed action moves RFC 6346 to the Standards Track, as Proposed Standard.
