Padavan固件使用DNSPod解析IPV6

核心命令

在 Padavan 固件内，高级设置，系统管理，控制台位置输入

1	ip -6 neighbor show \| grep 95:8F:15:B3:6B:68 \|grep -v fe80\| awk '{print $1}' \| head -1

第二段 grep 后面跟需要查询的设备MAC地址，即可获取对应设备的公网 ipv6 地址，也适用于其他 linux 系统

可以结合上面 DNSPod 代码在路由器进行解析，每 10 分钟检测一次

1	/10 * * * /etc/storage/dnspod.sh

开启 ipv6 防火墙指定端口

1 2	ip6tables -I FORWARD -p tcp --dport 5001 -j ACCEPT ip6tables -I FORWARD -p tcp --sport 5001 -j ACCEPT

完整代码

放在了/etc/storage目录下，记得修改权限

1	chmod 777 /etc/storage/dnspod.sh

需要自行修改倒数第1行和倒数第4行，以及14行的MAC地址，更新成功后会自行刷新路由器的 dns 缓存
