前有深圳电信 DNS 污染 /t/962196 ,现在广州电信也有同样的情况了
无论是广州东区还是西区,得到的解析结果都是污染的
nslookup cloudflare.com 202.96.128.166

Server: ns.szptt.net.cn

127.0.0.1
用广东电信 IPv6 的 DNS:
nslookup cloudflare.com 240e:1f:1::1
Server: UnKnown
Address: 240e:1f:1::1
Name: cloudflare.com
Addresses: ::1
127.0.0.1
nslookup api.cloudflare.com 240e:1f:1::1
Server: UnKnown

127.0.0.1
全部都污染了。

@JoeoooLAI #55 上周心血来潮把 ipv6 的 DNS 启用了, 昨天在家直接浏览器打开收藏夹的群晖 ddns 的 user.myds.me 域名无法访问, 鉴于之前听说群晖停止 quick connect 服务还以为是 myds.me 的域名也停止服务了, 一通操作把 ddns 的域名换成了 dnspod 上注册的
然后再 nslookup 域名发现是被广东电信的 ipv6 dns 240e:1f:1::1 解析到了 127.0.0.1...换成阿里 ipv6 dns 就正常了. 简直丧心病狂 |
