我在本地计算机上使用 CoreDNS 配置了 DoT，上游服务器为 Google （ 8.8.8.8，8.8.4.4 ），端口 853
然而我发现，所有的域名都能正常解析，但是 spi.dod.mil 这个域名还是解析不出来
日志如下：
nslookup spi.dod.mil
服务器: UnKnown
Address: 127.0.0.1
DNS request timed out.
timeout was 2 seconds.

*** 请求 UnKnown 超时
CoreDNS 日志：

这个域名在某些国外 VPS 上也解析不出来，比如亚马逊 Lightsail
日志：
Server: 127.0.0.53
Address: 127.0.0.53#53
** server can't find spi.dod.mil: SERVFAIL
但在有些海外 VPS 服务器上有解析的出来：
Server: 127.0.0.53
Address: 127.0.0.53#53
Non-authoritative answer:
spi.dod.mil canonical name = www.spi.hpc.mil.
www.spi.hpc.mil canonical name = www.spi.afrl.hpc.mil.
www.spi.afrl.hpc.mil canonical name = tensweb1.afrl.hpc.mil.

 | 1 zro 2020-03-13 11:16:23 +08:00 直接用 114 查也这样啊。 你的域名 NS 没设好吧？？ |

 | 3 mason961125 2020-03-13 12:03:45 +08:00 dod.mil... 你看着这域名就不觉得是人家不想给你解析么？ |
 | 4 Xi 2020-03-13 12:04:33 +08:00 nslookup spi.dod.mil 服务器: localhost Address: 127.0.0.1 非权威应答: 名称: spi.dod.mil www.spi.hpc.mil www.spi.afrl.hpc.mil 正常建议试试换掉 8 谷歌的 dns，试试 1.1.1.1 ？ |
 | 5 Kelan 2020-03-13 12:54:02 +08:00 .mil 的域名，不给解析似乎也合理把.. |
