The article explains the escalating costs of IPv4 addresses, outlines the technical and operational benefits of IPv6, shares a step‑by‑step migration experience with Debian, NAT64, and Docker, and highlights practical pitfalls and solutions for running production services on IPv6.
DPVS is an open‑source, DPDK‑based user‑space load balancer that achieves line‑rate throughput by assigning each worker to a dedicated CPU core and NIC queue, provides lock‑free per‑CPU data structures and multiple forwarding modes including NAT64, and simplifies maintenance while supporting IPv4/IPv6 in large‑scale production deployments.
This article explains how UCloud addresses IPv4 limitations by deploying a free IPv6 conversion service built on stateful NAT64 and programmable P4 switches, detailing the strategic rollout, system architecture, high‑availability and security mechanisms, load‑balancing algorithms, P4 table optimizations, and performance test results.
This article explains IPv6 socket programming fundamentals, focusing on NAT64/DNS64 transition mechanisms, handling various IP‑stack combinations, and detecting client support, with practical code examples and workflow diagrams relevant to iOS 9 and broader platforms.
