反向 DNS 未传播

反向 DNS 未传播

我在名称服务器中为服务器定义了反向 DNS 区域muq.ac.ir,该服务器响应域muq.ac.ir服务器的名称解析。然后我为 IP 地址添加了一个80.191.92.199值为 的ptr 记录muq.ac.ir。然而,大约 12 小时后,我仍然无法反向查找我的域。
我是否遗漏了有关 DNS 服务器的某些信息,或者我的服务器不负责反向查找?
还是 DNS 服务器仍未传播?

您的 DNS 服务器不负责此区域。您可以使用 dig 请求进行检查:

$ dig 92.191.80.in-addr.arpa 

; <<>> DiG 9.8.4-rpz2+rl005.12-P1 <<>> 92.191.80.in-addr.arpa

公共地址由 RIPE 提供,他们将地址委托给其他公司。如果您不是这块 IP 地址的所有者,那么您应该要求创建向您提供此公共 IP 的 PTR 公司。一般来说,它是互联网服务或托管提供商。

以下是有关该 IP 地址块的所有者以及该块的 BGP AS 编号的信息:
