 * All secondary network interfaces employed by workloads with the use of MULTUS MUST support Dual-Stack IPv4/IPv6.
 
+For platform using IPv4 addressing for CNI interfaces, and a NAT46/64 implementation in Services Proxy/Load Balancer for Ingress & Egress traffic. Workloads shall support this requirement.
+
 * Instantiation of a workload (via Helm chart or Operators or otherwise) shall result in a fully-functional workload ready to serve traffic, without requiring any post-instantiation configuration of system parameters
 
 * Workloads shall implement service resilience at the application layer and not rely on individual compute availability/stability
