设置反向DNS记录 [英] Setting up Reverse DNS Records

问题描述

这个问题不是直接编程相关的，但是我需要我的服务器通过垃圾邮件过滤器让我的应用程序正常工作。我和我的ISP谈到rDNS，技术支持的人告诉我，如果我写了一个电子邮件，他们应该添加到我们的DNS记录，他们会这样做。我的问题：

This question is not directly programming related but I need my Server to pass Spam filters for my app to work properly. I talked to my ISP about rDNS and the guy from tech-support told me if I write an email with what they should add to my DNS record they would do that. My question:

如果我的主机名是，该怎么办？ http://niklasfi.de ，我的是78.31.67.216？

What should I tell him to add if my hostname is "http://niklasfi.de" and my is 78.31.67.216?

谢谢答案。我试图在网上搜索，但我只是一个单一的ISP的非常具体的陈述。

Thanks für the answers. I tried searching on the Web but i only very specific anwers concerning a single ISP.

推荐答案

反向DNS只是一个记录，查找是从您的IP地址找到您的主机名。所以你应该要求他为你的主机名添加一个反向的IN-ADDR条目78.31.67.216。

reverse DNS is simply a record where the lookup is to find your host name from your IP address. So you should ask him to add a reverse IN-ADDR entry for 78.31.67.216 with your hostname.

这将是：216.67.31.78.in-addr.arpa niklasfi .de

this would be: 216.67.31.78.in-addr.arpa niklasfi.de

这些也称为PTR记录。

These are also known as PTR records.
