正向和反向DNS区域分配不同的NameServers

Question

如果正向和反向DNS区域分配了不同的NameServers，那么反向DNS查找是否会解决/工作？

注意：将此视为Google Cloud DNS服务的默认行为。

Answer 1

是。正向和反向区域是完全独立的区域，它们之间没有技术联系。唯一的联系是一个数据与另一个数据的知名关系。

感谢Calle花时间查看我的查询。但是在下面我终于得到了回答我的问题 - ＆gt; http://www.dnsstuff.com/reverse-dns-faq

认为值得在这里分享：

非常常见的神话：

* Myth: If you have a reverse DNS entry listed in your DNS server, you have reverse DNS properly set up.
  Fact: This is often not the case. You need TWO things in order to have your DNS set up properly:
      o 1. Your DNS servers (or your ISP's) MUST have the reverse DNS entries set up ("25.2.0.192.in-addr.arpa. PTR host.example.com").
      o 2. AND your ISP or bandwidth provider MUST set up the reverse DNS on their end, so that DNS resolvers around the world will know that your DNS servers are the ones to go to when looking up the reverse DNS for your IP addresses.
