偶然发现 X 部分域名解析到了 Cloudflare CDN:
> nslookup t.co.cdn.cloudflare.net
Server: 127.0.0.53
Address: 127.0.0.53#53
Non-authoritative answer:
Name: t.co.cdn.cloudflare.net
Address: 162.159.140.229
Name: t.co.cdn.cloudflare.net
Address: 172.66.0.227
Name: t.co.cdn.cloudflare.net
Address: 2606:4700:7::e3
Name: t.co.cdn.cloudflare.net
Address: 2a06:98c1:58::e3
> nslookup pbs.twimg.com.cdn.cloudflare.net
Server: 127.0.0.53
Address: 127.0.0.53#53
Non-authoritative answer:
Name: pbs.twimg.com.cdn.cloudflare.net

Name: pbs.twimg.com.cdn.cloudflare.net
Address: 104.18.8.251

主域名 x.com 也有对应的 CNAME 接入,只是没有 AAAA 记录:
> nslookup x.com.cdn.cloudflare.net
Server: 127.0.0.53
Address: 127.0.0.53#53
Non-authoritative answer:
Name: x.com.cdn.cloudflare.net
Address: 172.66.0.227
Name: x.com.cdn.cloudflare.net
Address: 162.159.140.229
手动把 x.com 解析过去 IPv6 地址,可以正常打开首页。不过好像没有什么实际用途。。
