powershell 批量添加dns记录

在系统运维实践中经常有大量添加dns记录的需求，如果手动添加，那就非常耗时而且容易出错。Windows powershell对这一块支持的特别好，我参考一些技术文档写了如下脚本，使用起来非常方便。供大家参考：

#dns server name
$servername = "dcname"

#domain name
$domain = "domain.com"

#dnscreate.csv
#
#   |computer | ip             |
#   | linuxsrv45 | 192.168.127.45 |

$dns_list = Import-Csv D:\dnscreate.csv

$dns_list | %{
$computer = "$($_.computer).$domain"
$addr = $_.ip -split "\."
$rzone = "$($addr[2]).$($addr[1]).$($addr[0]).in-addr.arpa"
dnscmd $servername /recordadd $domain "$($_.computer)" A "$($_.ip)"
dnscmd $servername /zoneadd $rzone /primary
dnscmd $servername /recordadd $rzone "$($addr[3])" PTR $computer
}
