好吧，我要预先声明这个问题对于这个媒体来说可能过于复杂（细节量而不是复杂性）。但我认为这是最好的起点。
我正在尝试建立一个概念验证项目，而我的 BIND 配置是我的第一个大障碍。我想在 3 个物理盒子上设置 3 个 DNS 服务器。 这些盒子都不需要解析公共地址，这只是内部的。我已经阅读了（主要是）优秀的 DNS & BIND 第 5 版书中如何设置内部根。但是我对他们示例的翻译不起作用。所有 IP 都是 RFC 1918 不可路由的。
框 1 对box1.bogus域中的地址具有权威性，框 2 对box2.bogus域中的地址具有权威性。框 3 将作为域bogus的内部根和 TLD 服务器。
当前未解决的问题：
我在框 1 和框 2 上有一个提示文件，其中包含根区域的 NS 定义的单个NS记录。此外，还有一条A记录将 NS 转换为根的 ip。如果我
dig .从框 1 中得到一个带有 NS 名称的权限部分，而不是答案和附加记录部分。因此，我无法从框 1 中实际解析根服务器的 IP。如果我将我
/etc/resolv.conf的 from box 1 直接指向根服务器并执行 a，dig box1.bogus我将获得 ns.box1.bogus答案记录和附加部分中的翻译。但是在下一次迭代中（什么时候应该得到 A 记录）我得到dig: couldn't get address for ns.box1.bogus
显然我的配置不正确。我看不到将它们附加到此帖子的方法，因此，如果人们想逐步完成此操作，我会将它们剪切'n'粘贴到此问题的评论中。否则，我愿意与“DNS 人员”一起“离线”，以找出我缺少“。”的地方。或者有太多！
我个人认为网络可以使用另一个不使用 Movie-U 示例的内部根示例。
好的，如果我们要这样做，那么我们应该使用一个具体的例子吧？我在专用 VLAN 上设置了 3 台机器来进行测试。作为健全性检查，我将所有相关配置配对，在可能的情况下进行压缩，并重新部署 2 个名称服务器。我暂时忽略了 Scratchy。结果与上述相同。这是配置和初始挖掘输出。
