为什么使用 Google 的 DNS 解析 m10.music.126.net 响应的 127.0.0.1 ?

[xarrow]

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

@myguybetter 从 https://dns.google.com 页面上查询也是指向 127.0.0.1

[a2213108]

@xarrow https://dns.google.com/query?name=m10.music.126.net&type=A&dnssec=true&ecs=114.114.114.114
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

应该是版权问题

[lydasia]

照这么说，在海外听不用翻回去，直接 hosts 搞定？

[Love4Taylor]

@lydasia #10 验证地区的 可不是这个域名...

[UnisandK]

@lydasia
@Love4Taylor

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

[Love4Taylor]

@UnisandK #12 顶多桌面端能用 移动端不是已经用 httpdns 很久了么....

[UnisandK]

@Love4Taylor 移动端没试过了，我都电脑上听的

[bclerdx]

@a2213108 国外 ip 太多了，怎么做到瓶壁的？

[song4]

@bclerdx 可以通过 IP 反查地理位置呀
