[DNS] 关于 adguardhome 的一点疑问

发表于

我路由器刷了 openwrt ,开了 openclash 和 adguardhome ,openclash redir-host 模式,劫持本地 dns ,使用 dnsmap 转发,自定义上游 dns 服务用的 adguardhome ,目前出现一个问题,就是无法访问 https://test.ustc.edu.cn (中国科学技术大学测试网站),但是 https://test6.ustc.edu.cn (纯 ipv6 )就可以。在 adguardhome 上看查询日志,发现用手机访问 https://test.ustc.edu.cn 时会返回 ipv6 的 dns 结果,且没有返回具体 ip ,如下图: 65f14d8198f6e431.png

但是这个网站应该是只有 ipv4 的,不知道为何返回 AAAA 记录。但是当我用 Mac 访问时,返回的是正确的 ipv4 地址: 4a4574385a894924.png 但是还是无法访问网站

我用 nslookup 和 traceroute 都是正常的,但是 ping timeout ,openclash 里面也没有看到相关的访问日志

有没有大佬能解答一下咋回事呢。。如果只是这个网站无法访问还行,但是就怕还有其他正常网站不行,所以想要解决一下这个问题。。
