Abstract:

   For the IPv6 transition, IPv6-only is considered the final stage
   where only IPv6 protocol is used for transport while maintaining
   global reachability for both IPv6 and IPv4 services.  This document
   introduces a framework for a multi-domain IPv6-only underlay network
   from the perspective of network operators.  In particular, it
   proposes stateless address mapping as the basis for enabling IPv4
   service data transmission in a multi-domain IPv6-only environment
   (i.e., IPv4-as-a-Service).  It describes the methodology of stateless
   IPv4/IPv6 mapping, illustrates the behaviors of network devices,
   analyzes the options of IPv6 mapping prefix allocation, and discusses
   the security considerations.  This framework is not intended to
   replace existing IPv6-only technologies, but rather to leverage or
   remain compatible with them.
