OpenWRT中只能获取到局域网客户端fe80开头的地址

[moreoronce]

Description

使用命令行模式
通过SSH在OpenWRT中执行
ip -6 neigh | awk '/2c:f0:5d:3e:b6:1b/{print $1}' | awk '/240/'
返回240开头的IPv6地址

在DDNS-GO中使用相同的命令，log显示
Get IPv6 result failed! Command: /bin/bash -c ip -6 neigh | awk '/2c:f0:5d:3e:b6:1b/{print $1}' | awk '/240/', Stdout: ""
Stdout为空

去掉240的过滤条件后，可以获取到客户端的IPv6地址，但是是fe80开头的地址

期望效果：
可以获取到局域网内客户端的240开头地址。
