    5 为什么用 win 的 dns ?
    答:
    5.1 主要因为有 powershell。
    我记得 bind 无法用命令添加 a 记录等,并立即生效。这样的话拍马也赶不上 powershell 了!你要搞个程序去修改 dns 区域文件,然后 reload 分区。这样性能很差吧。
    powershell 命令管理 dns 是内存操作。主要用到的命令就这四个:
    Add-DnsServerResourceRecordA,Add-DnsServerResourceRecordCName,Get-DnsServerResourceRecord,Remove-DnsServerResourceRecord

    5.2 win 的 dns 性能无问题:我记得 bind 是多进程的程序,可以用多核跑,无性能制约。而 win2000 中说 win 的 dns 比 bind 效率高。
    dns 还都是 10 年前都成熟的东西。退一万步来讲,win 的 dns 玩一千个以下的 ip 解析,不会有性能问题。

    5.3 可以用 win 做主 dns 服务器,linux+bind 做缓存。win 放内网,linux 放外网,只从外网 dns 缓存取数据。


    ------------------------win2012r2 中,用 powershell 管理 dns 服务器的,命令列表--------------------------------
    共计 100 条指令,即 100 招,下面演示如何用其中 4 招秒杀 bind 的。
