DNS 解析在 3 月下旬工作正常，但现在，一些解析器（我在 NAT 后面的 LAN 上的解析器，以及我的 ISP RCN 的解析器）在这个区域的主机名上有问题，而其他（例如，谷歌的 8.8.8.8）则没有。
这些 DNS 查询未被粉饰。您可以查询“.mail.eo.outlook.com”区域中的任何主机名。
谷歌可以解决它。. .
$ dig anything.mail.eo.outlook.com @8.8.8.8

虽然我的解析器和 RCN 不能：
$ dig anything.mail.eo.outlook.com @192.168.42.108
; <<>> DiG 9.8.3-P1 <<>> anything.mail.eo.outlook.com @192.168.42.108

;; global options: +cmd
;; connection timed out; no servers could be reached
解析器在其他区域上可以正常运行：
$ dig +short www.google.com @192.168.42.108

如果我一步一步地挖掘。. .
谁是 outlook.com 的授权者？让我们询问 192.35.51.30（即 f.gtld-servers.net）。

向其中一个名称服务器询问答案...

所以该区域已委托，让我们查找委托 NS 的 IP...
$ dig +short ns1-prodeodns.glbdns.o365filtering.com
65.55.169.42
207.46.100.42
