最近项目开发需求,需要设备支持IPV6协议,用过,W5500。发现WIZnet 推出新款:W6100模组, 是一款支持 IPv4/IPv6 双核的新一代全硬件以太网 TCP/IP 协议栈控制器。W6100 在 WIZnet TCP/IP 协议栈 IPv4 的基础上增加了 IPv6,并且支持 TCP,UDP,IPv6,IPv4,ICMPv6,ICMPv4,IGMP,ARP 以及 PPPoE 等协议。同时其内部集成了 10/100M 以太网数据链路层(MAC)以及物理层(PHY),能够更加简单快速地实现嵌入式设备的联网功能。 IPv6三种转换技术当前,网站应用IPv6升级改造的技术路线主要有双栈、隧道和转换等三种技术。对嵌入式系统用单芯片解决。目前ESP32对IPV6支持。
武汉、西安、沈阳、南京、重庆、杭州、贵阳·贵安、福州8个互联网骨干直联点全部完成了IPv6升级改造,支持互联网间IPv6流量交换。加上2018年完成的北京、上海、广州、郑州、成都等5个骨干网直联点,我国全部13个骨干网直联点全部完成了IPv6改造。我国IPv6地址拥有数量稳定增加,截至2020年1月,我国已申请了47851块(/32)IPv6地址,位居世界第二。IPv6活跃用户量大幅提升。截至2020年1月,我国IPv6活跃用户数达2.7亿,占互联网网民总数的31%,相比行动计划实施前,增长了近100倍。全国已有11.93亿LTE用户、1.99亿固定网络用户,合计13.92亿用户获得了IPv6地址。
