I believe that I found the correct answer through this dig How To. I was able to look up the SPF records on a specific DNS, by using the following query:
The dig utility is pretty convenient to use. The order of the arguments don't really matter.I'll show you some easy examples. To get all root name servers use
# dig
To get a TXT record of a specific host use
# dig example.com txt
# dig host.example.com txt
To query a specific name server just add @nameserver.tld
# dig host.example.com txt @a.iana-servers.net
The SPF RFC4408 says that SPF records can be stored as SPF or TXT. However nearly all use only TXT records at the moment. So you are pretty safe if you only fetch TXT records.
I made a SPF checker for visualising the SPF records of a domain. It might help you to understand SPF records better. You can find it here: http://spf.myisp.ch

我相信我通过这个挖掘方法找到了正确的答案。我能够使用以下查询查找特定 DNS 上的 SPF 记录：

dig 实用程序使用起来非常方便。参数的顺序并不重要。我将向您展示一些简单的示例。
要获取所有根名称服务器，请使用
要获取特定主机的 TXT 记录，请使用
要查询特定名称服务器，只需添加 @nameserver.tld
SPF RFC4408 表示 SPF 记录可以存储为 SPF 或 TXT。然而，目前几乎所有的记录都只使用 TXT 记录。因此，如果您只获取 TXT 记录，那么您是非常安全的。
我制作了一个 SPF 检查器来可视化域的 SPF 记录。它可能会帮助您更好地了解 SPF 记录。您可以在这里找到它：
