Techniques presented herein provide a variation of Internet Engineering Task Force (IETF) Request For Comments (RFC) 8505 to register stub prefixes to a fabric, and also of RFC 6877 to combine Network Address Translation (NATing) and Internet Protocol (IP) version 4 (v4) to v6 and also v6 to v4 translation. The new operation provides for the ability to transport IPv4 cloud-native application flows between applications and services over an IPv6-only fabric without a change in the containers running the applications and services. The techniques further provide for the ability to load-balance services over the Internet, using a variation of RFC 1794 to obtain a /96 route to the cluster location and RFC 2391 to distribute the load over service instances (e.g., pods).
