1.  Introduction

   This document proposes that Stateful NAT64: Network Address and
   Protocol Translation from IPv6 Clients to IPv4 Servers ([RFC6146]) is
   advanced Internet Standard, following RFC6410 ([RFC6410]).

   (1) There are at least two independent interoperating implementations
   with widespread deployment and successful operational experience.

   Stateful NAT64 ([RFC6146]) has been widely implemented by at least a
   dozen of vendors and its being used in commercial deployments by
   hundreds of millions of devices.

   (2) There are no errata against the specification that would cause a
   new implementation to fail to interoperate with deployed ones.

   Stateful NAT64 ([RFC6146]) has 2 errata, none of which would cause
   new interoperability problems.

   (3) There are no unused features in the specification that greatly
   increase implementation complexity.

   There are no unused features.

   (4) If the technology required to implement the specification
   requires patented or otherwise controlled technology, then the set of
   implementations must demonstrate at least two independent, separate
   and successful uses of the licensing process.

   There is a pending Patent that offers Reasonable and Non-
   Discriminatory License to All Implementers with Possible Royalty/Fee,
   however it hasn't constituted an issue for multiple independent
   implementations.
