        Title           : 464XLAT/NAT64 Optimization
        Authors         : Jordi Palet Martinez

   This document proposes possible solutions to avoid certain drawbacks
   of IP/ICMP Translation Algorithm (SIIT) when the destinations are
   already available with IPv6.  When SIIT is used as a stateless NAT46
   and IPv4-only devices or applications initiate traffic flows to dual-
   stack services (in the operator network or Internet), those flows
   will be translated back to IPv4 by a NAT64.  Avoiding this dual-
   translation will significantly reduce the usage of the NAT64 and the
   relevant logging, which may be a high impact when traffic flows are
   towards CDNs, caches or similar resources.  This is the case for
   464XLAT and MAP-T.
