反向DNS错误

Question

今天，我将我的DNS和名称服务器更改为Cloudflare。之后，pingdom给出了一些奇怪的DNS错误。我在网上搜索，但找不到解决办法。这些错误是：

Could not find reverse address for 64.233.162.26 (26.162.233.64.in-addr.arpa.).

PTR record(s) for the address could not be found in the .arpa-zone. (ip6.arpa. for IPv6 addresses and in-addr.arpa. for IPv4).

Could not find reverse address for 64.233.189.27 (27.189.233.64.in-addr.arpa.).

有人能帮忙吗？

谢谢!

Answer 1

DNS服务器有缓存，每次更改都需要时间才能使所有DNS服务器完全正常工作。几个小时后就能修好。您可以尝试nslookup -type=ns 64.233.162.26来获得一个非缓存的答案。

Answer 2

正如我在前面的评论中提到的，问题中提到的地址属于谷歌，因此这些地址是否有反向PTR记录最终取决于谷歌。

我还没有真正了解所有这些地址到底是什么(也许是Pingdom提供给您的信息？)但是，例如，64.233.189.26似乎是与ASPMX4.GOOGLEMAIL.COM相关的地址之一。我是否正确地假设您在此域上使用谷歌应用程序？

总而言之，缺乏反向记录真的会给你带来任何问题吗？如果是，请与服务提供商(Google)联系。
