    这是一个创建于 2675 天前的主题,其中的信息可能已经有所发展或是发生改变。

    使用 Google DNS 来解析m10.music.126.net响应127.0.0.1,而使用 114 的 DNS 解析返回正常,导致使用 8.8.8.8 网易音乐播放不了

    edns 用国内 ip 就能解析,网易云根据客户端 ip 判断的,国外 IP 都返回 127.0.0.1

    120.52.72.23 music.163.com
    120.52.72.23 m10.music.126.net

    用的联通的缓存服务器,用法大概就 curl 120.52.72.23 -H 'Host: ip.cn' ,不支持 https
    放不出来可以多刷新两遍试试,我这儿是成功的
