Abstract:
   IP/ICMP Translation Algorithm (SIIT) can be used to provide access
   for IPv4-only hosts or applications to IPv4-only or dual-stack
   destinations over IPv6-only infrastructure.  In that case, the
   traffic flows are translated twice: first from IPv4 to IPv6
   (stateless NAT46 at the ingress point to the IPv6-only
   infrastructure) and then from IPv6 back to IPv4 (stateful NAT64, at
   the egress point).  When the destination is IPv6-enabled, the second
   translation might be avoided.  This document describes a possible
   optimization to 464XLAT and MAP-T to avoid translating IPv6 flows
   back to IPv4 if the destination is reachable over IPv6.  The proposed
   solution would significantly reduce the NAT64 utilization in the
   operator's network, increasing the performance.
