How Do You Build an IPv4/IPv6 Gateway on STM32 Using W6100? Register-Level TCP Behavior and Dual-Stack Gateway Architecture Explained (STM32와 W6100으로 IPv4/IPv6 게이트웨이를 설계하면 무엇이 달라지는가?) Summary (40–60 words) This article explains how to design an embedded IPv4/IPv6 gateway using an STM32 microcontroller and the WIZnet W6100 Ethernet controller. By analyzing register-level TCP behavior, socket lifecycle management, and dual-stack data flow, it shows how hardware TCP/IP offloading enables reliable, future-proof gateway implementations for industrial and IoT systems. 1. Why IPv4/IPv6 Gateways…
