正向和反向域名系统区域被分配不同的NameServers

Question

如果向前和反向DNS区域分配了不同的NameServers，反向DNS查找是否可以解析/工作？

注意:观察到这是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，它们之间没有技术上的联系。唯一的联系是一个数据库中的数据与另一个数据库中的数据具有众所周知的关系。

感谢Calle花时间研究我的查询。但在下面我终于得到了我的问题的答案--> http://www.dnsstuff.com/reverse-dns-faq

我觉得在这里分享是值得的：

非常常见的误区：

* 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.
