任何DNS区域都可以具有该区域本身的任何DNS记录(在绑定配置文件中,该记录标记为@)。实际上-让我问这个-根区域可以有一个@来描述自己吗?IE浏览器可以@有地址记录吗?我不明白为什么不能。 那将是一个很酷的地址。“ http://./ ”
“根”区域只是一个名为“。”的区域。目前,该区域中有一堆名称服务器。这些名称服务器的地址以文本文件的形式分发。手动将这个文本文件或类似文件输入许多典型的递归名称服务器。
放置一个“。” 名称末尾告诉您的本地解析器,您输入的名称是“ 完全限定 ”域名,这意味着它只是您要查找的名称而已。通常,我们使用不合格或其他含糊的名称(例如“ www”)来表示“ www.of.the.place.I.work”,其中本地DNS解析程序将“ of.the.place.I.work”作为“ dns”域”或“搜索域”。
这些根级域服务器具有“ 顶级 ”域列表,这些列表大致映射到80年代研究人员如何使用互联网和国家/地区的旧抽象,以及“ 基础结构”的顶级域。这些顶级域中的每一个都有一堆名称服务器,其中包含该域中实际区域的列表,因此对maps.google.com的请求首先转到根服务器,该服务器会传递出一个有关的名称服务器列表。 com,当被问到时,其中一位知道哪个名称服务器具有google.com的记录,而其中一位知道www.google.com的特定记录。
因此,您所需要做的就是说服为国家或组织运行TLD的人输入.zone的地址记录,而不仅仅是google.zone,这是您的黄金。
目前,以下顶级域具有地址记录(尽管并非所有运行的Web服务器)
ac has address 193.223.78.210
ai has address 209.59.119.34
bi has address 196.2.8.205

并且以下具有MX记录(因此user @ TLD。是潜在的可交付地址)

因此,从理论上讲,您可以将电子邮件发送到pope @ va。它将正确交付...
如果您使用不同的根服务器,您将对Internet上存在的内容有不同的看法。我所做的所有本地解决方案都针对使用“ dnscache ”的本地系统,该系统直接进入根服务器。许多其他解析DNS服务器将询问另一个本地DNS服务器,而不是询问根服务器。
