DNS添加/修改/查询/删除A记录

如果DC部署在不同站点，在其中一台DNS新建A记录后，快速复制到其他站点DNS方式如下：

1.先对AD进行站点间复制

2.在目标DC上运行命令：dnscmd /zoneupdatefromds ZoneName，比如 dnscmd /zoneupdatefromds abctest.test3.com，A记录会立即刷新出来

 

#查询DNS可用类

Get-WmiObject -Namespace root\MicrosoftDNS -List

 

#查询所有资源记录

$mydns = [WMIClass]"ROOT\MicrosoftDNS:MicrosoftDNS_ResourceRecord"
$mydns = [WMIClass]"\\$Server\ROOT\MicrosoftDNS:MicrosoftDNS_ResourceRecord"

 

#查询已有区域

gwmi -Namespace root\microsoftdns -Class MicrosoftDNS_zone |select ContainerName

 

#查询 ddv.com区域下的所有A记录

Get-WmiObject -Namespace root\MicrosoftDNS -class microsoftdns_atype | ? {$_.ContainerName -eq "ddv.com"} |Select TextRepresentation

 

#查询单条A记录

#查询 bb.ddv.com 的A记录
$ARecord = Get-WmiObject -Namespace root\MicrosoftDNS -class MicrosoftDNS_ResourceRecord -filter "containername='ddv.com' AND OwnerName='bb.ddv.com'"

#查询 bb.ddv.com 的A记录
$ARecord = Get-WmiObject -Namespace root\MicrosoftDNS -class microsoftdns_atype | ? {$_.OwnerName -eq "bb.ddv.com"}

 

#修改A记录

#修改A记录 bb.ddv.com 的IP指向为172.0.0.23
$ARecord = Get-WmiObject -Namespace root\MicrosoftDNS -class microsoftdns_atype | ? {$_.OwnerName -eq "bb.ddv.com"} 
$ARecord.Modify($ARecord.TTL,"127.0.0.223")

 

 #删除A记录

#删除A记录 bb.ddv.com 
$ARecord = Get-WmiObject -Namespace root\MicrosoftDNS -class microsoftdns_atype | ? {$_.OwnerName -eq "bb.ddv.com"}
$ARecord.delete()

 

#添加A记录

#添加单条A记录 bb.ddv.com IN A 127.0.0.3
$dnsServerName=""
$containerName="ddv.com"
$dns = [WMIClass]"ROOT\MicrosoftDNS:MicrosoftDNS_ResourceRecord"
$dns.CreateInstanceFromTextRepresentation($dnsServerName, $containerName, "bb.ddv.com IN A 127.0.0.3")

#批量添加Ａ记录
$dnsServerName=""
$containerName="ddv.com"
$dns = [WMIClass]"ROOT\MicrosoftDNS:MicrosoftDNS_ResourceRecord"
Get-Content D:\dnsListFile.txt | Foreach-Object {$dns.CreateInstanceFromTextRepresentation($dnsServerName, $containerName, $_)}

 dnsListFile.txt内容如下：

 aaa.ddv.com IN A 127.0.0.1
 bb.ddv.com IN A 127.0.0.2

 

#查询转发服务器

gwmi -Namespace "root\MicrosoftDNS" -class "MicrosoftDNS_Server" | Select-Object -ExpandProperty Forwarders

 

=====================================================================

#修改DNS A记录
$ZoneName = "yxp.com"
$HostName = "ldaptest"

$As = Get-DnsServerResourceRecord -ZoneName $ZoneName | ? {$_.HostName -eq $HostName} |sort RecordData
$NewRecord = $As.Clone()
$NewRecord.RecordData.IPv4Address ="10.10.3.3"

Set-DnsServerResourceRecord -ZoneName $ZoneName -OldInputObject $As -NewInputObject $NewRecord


#添加A记录
Add-DnsServerResourceRecordA -Name $HostName -ZoneName $ZoneName -AllowUpdateAny -IPv4Address $IP  

 如果在区域aa.com下新建了子区域bb，则在添加A记录的时候，ZoneName保持不变，仍为aa.com，HostName原来为host01，则需要修改为 host01.bb，然后再通过命令添加即可 Add-DnsServerResourceRecordA -Name $HostName -ZoneName $ZoneName -AllowUpdateAny -IPv4Address $IP  

 

#修改A记录TTL值
$OldObj=Get-DnsServerResourceRecord  -ZoneName "xx.com" -RRType "A"

foreach ($record in $OldObj)
{
$NewObj = $record.Clone()
$NewObj.TimeToLive = [System.TimeSpan]::FromHours(6)
Set-DnsServerResourceRecord  -NewInputObject $NewObj -OldInputObject $record -ZoneName "xx.com" -PassThru
$NewObj=$Null
$record=$Null
}
