我的公司运行内部 DNSmycompany.example
网络上有一台机器我需要查找,但我忘记了它的名字。如果我能看到一个列表,它可能会唤起我的记忆。
我如何列出所有的域名记录mycompany.example
?
答案1
回答
对于你关于列出 CNAME 的具体问题,简短的回答是,你不能在未经许可的情况下进行区域传输(请参阅如何列出给定域的所有 CNAME 记录?)。
也就是说,如果您公司的 DNS 服务器仍然支持 ANY 查询,您可以使用 dig 列出其他记录,方法如下:
dig +noall +answer +multiline yourdomain.yourtld any
这些+noall +answer +multiline
……是严格可选的,只是输出格式标志,以使输出更易于人类阅读(参见挖掘手册页)。
例子
$ dig +noall +answer +multiline bad.horse any
返回:
bad.horse. 7200 IN A 162.252.205.157
bad.horse. 7200 IN CAA 0 issue "letsencrypt.org"
bad.horse. 7200 IN CAA 0 iodef "mailto:[email protected]"
bad.horse. 7200 IN MX 10 mx.sandwich.net.
bad.horse. 7200 IN NS a.sn1.us.
bad.horse. 7200 IN NS b.sn1.us.
bad.horse. 7200 IN SOA a.sn1.us. n.sn1.us. (
2017032202 ; serial
1200 ; refresh (20 minutes)
180 ; retry (3 minutes)
1209600 ; expire (2 weeks)
60 ; minimum (1 minute)
)
注意事项(RFC8482)
注意,自 2019 年左右以来,大多数公共 DNS 服务器已停止ANY
有效回答大多数 DNS 查询。有关背景信息,请参阅:RFC8482 - 告别 ANY
如果ANY
查询没有枚举多个记录,则唯一的选择是请求每个记录类型(例如 A、CNAME 或 MX)。

一个更容易记住(并且更具信息量)的命令是:
> dig google.com ANY
返回以下内容:

答案3
尝试:
dig @ns.example.com -tAXFR example.com
这可能有效,也可能无效。许多 DNS 服务器会拒绝DNS 区域传输就像这样。有关更多信息,请参阅AXFR 协议的工作原理
答案4
dig domain ANY
应该会给你所有记录。我写应该,因为它取决于使用的 DNS 服务器。dig gmx.de ANY 和我的 Telekom-DNS DNS 服务器 217.237.148.102 17.237.151.115 只给出
