有一些 IP 地址nslookup无法解析（在 Windows 和 Linux 上）。

问题：

我可以找到主机名的IP，但反向查找失败。

PS C:\> nslookup.exe somehost2
Server:  corpdns.mydomain.com
Address:  10.248.2.1

Name:    somehost2.corp.mydomain.com
Address:  10.185.140.22

# Reverse lookup of the same IP fails:

PS C:\> nslookup.exe 10.185.140.22
Server:  corpdns.mydomain.com
Address:  10.248.2.1

*** corpdns.mydomain.com can't find 10.185.140.22: Non-existent domain

但是，Resolve-DnsNamePowerShell 命令返回反向查找的主机名。

PS C:\> Resolve-DnsName 10.185.140.22

Name                           Type   TTL   Section    NameHost
----                           ----   ---   -------    --------
22.140.185.10.in-addr.arpa.    PTR    1200  Question   somehost2

我在这里观察到两件不寻常的事情：

  1. 它来自问题部分
  2. 它返回没有 DNS 域的主机名。

对于其他 IP 地址（nslookup可以解析），我们看到它来自Answer部分并带有 DNS 域。

PS C:\> Resolve-DnsName 10.210.0.127

Name                           Type   TTL   Section    NameHost
----                           ----   ---   -------    --------
127.0.210.10.in-addr.arpa      PTR    1200  Answer     somehost1.corp.mydomain.com

顺便说一句，ping使用/a标志也可以成功解析 Windows 上的名称：

PS C:\> ping /a 10.185.140.22

Pinging somehost2 [10.185.140.22] with 32 bytes of data:
Reply from 10.185.140.22: bytes=32 time=6ms TTL=127
Reply from 10.185.140.22: bytes=32 time=12ms TTL=127

但是我在 Linux 中找不到等效的标志ping。

我的问题：

Resolve-DnsName与有什么ping不同nslookup？

我的主要问题是当我尝试在 Linux 中解析 IP 时。我已经尝试了几次nslookup并dig命令无济于事。Resolve-DnsName在 Linux 中有等效项吗？

澄清：

大多数 IP 地址也可以解决nslookup，问题仅出在我们环境中的特定主机子集上。

更新：nslookup调试模式

更新 #2

Resolve-DnsName当使用不同的标志时，这些系统会失败，例如：-DnsOnly, -NoHostsFile, -LlmnrNetbiosOnly（但确实适用于可以解析的其他 IP 地址nslookup）。
