从google工具箱中挖掘“creation-site-pro.fr”

问题出在哪里？

Answer 1

根据fr.区域，creation-site-pro.fr有两个名称服务器

creation-site-pro.fr.   172800  IN  NS  ns.xzave.net.
creation-site-pro.fr.   172800  IN  NS  ns.kimsufi.com.

在这两者中，ns.xzave.net.并不存在(xzave.net.甚至不是注册域)，ns.kimsufi.com.似乎拒绝查询。

虽然您的Debian服务器可能被正确地配置为响应区域上的查询，但它是不可访问的，因为它的主机名ns.xzave.net.没有指向它。

您可能想要考虑使用注册员提供的名称服务(如果他们提供的话)，或者确保服务器有一个指向它的正确的FQDN。您还需要整理另一个拒绝查询的服务器。
