OpenSDN, the evolution of Tungsten Fabric, continues to stand out with its dual IP stack support, enabling seamless IPv4 and IPv6 coexistence in modern networks. The recent R24.1 release introduces key enhancements, including full IPv6 support for metadata services, NAT66, and virtual DNS. These updates allow OpenSDN to support pure IPv6 environments without the need for IPv4 fallbacks, making it even more versatile for today’s networking demands. For an in-depth dive into these features, check out my blog for technical details on the implementation.
