Question

如今，无论何时使用WHOIS命令，都不会返回任何有用的信息。我通常必须去Godaddy，Dnsstuff或其他服务来获取数据。我理解其原因主要是垃圾邮件。

我只是想知道其他服务如何获取这些数据。他们是否使用不同类型的WHOIS命令？

Answer 1

当网络解决方案不再是唯一注册域名的地方时，裸露的whois停止返回完整记录。现在它的功能更像DNS，在某些地方为您提供了寻找权威信息的地方，如果您需要它，您必须去那里看看。

即便：

% whois stackoverflow.com
[Querying whois.verisign-grs.com]
[whois.verisign-grs.com]
   ...
   Domain Name: STACKOVERFLOW.COM
   Registrar: GODADDY.COM, INC.
   Whois Server: whois.godaddy.com
   ...

% whois stackoverflow.com@whois.godaddy.com
[Querying whois.godaddy.com]
[whois.godaddy.com]
...
Registrant:
   Stack Overflow Internet Services, Inc.
   1010 Disk Drive
   ...etc...

其他服务的业务是注册域名并从其域名注册人处获取信息。

Answer 2

这是the answer I posted on ServerFault。

假设您正在使用debian / ubuntu whois库，您的问题的简短答案是使用

$ whois -h whois.crsnic.net "domain google.com"

这是一个很长的答案。

.COM TLD是Thin WHOIS。当您执行WHOIS查询时，WHOIS工具首先向Verisign（主机名whois.crsnic.net）发送WHOIS查询，并从响应中提取推荐。

默认情况下，当您从域example.com查询Verisign时，Whois会在几个不同的对象（包括域名，注册商名称和名称服务器）中对字符串“example.com”进行非常广泛的搜索。

您可以通过指定关键字来优化查询，如Verisign文档中所述。 http://registrar.verisign-grs.com/whois/iframe/help.html?ppath=www.verisigninc.com/products-and-services/domain-name-services/whois&

上面的命令完全按照我的解释。它不是google.com，而是向Verisign发送完整的查询“domain google.com”。您必须显式传递-h标志，因为Whois会尝试猜测要从查询中查询的主机名，但它会失败，因为它无法将查询“domain google.com”识别为有效域。

这是命令的结果。

$ whois -h whois.crsnic.net "domain google.com"

虽然新的“密集”WHOIS政策现在要求所有新gTLD注册管理机构都运行一个密集的注册管理机构，但目前一些现有的注册管理机构（如.COM和.NET）尚未转变为“厚实”的WHOIS，但仍然运营薄弱注册表中。 - https://whois.icann.org/en/primer

对于.com和.net，使用简单的whois命令中的注册表的精简结果来查找注册商的whois服务器。

例如，

# whois google.com

   Domain Name: GOOGLE.COM
   Registry Domain ID: 2138514_DOMAIN_COM-VRSN
   Registrar WHOIS Server: whois.markmonitor.com
   Registrar URL: http://www.markmonitor.com

然后查询注册商以获得更粗的结果。

例如，

# whois google.com -h whois.markmonitor.com

在我看来（虽然我现在不想确定whois命令历史记录），但在某些时候，whois命令被修改为不会自动查询最初的瘦注册器结果注册表信息。

WHOIS命令没有返回有用的信息？
