Question

如果我运行命令

 $alldns = Get-DnsServerResourceRecord -computername dns-server -ZoneName "domain.com" -RRType "A"

它完美无缺，显示了ip地址：

pc2 A     1          10/24/2017 6:00:0... 00:20:00        192.168.1.149
Gaming               A          1          10/24/2017 6:00:0... 00:20:00        192.168.1.139
dc                    A          1          0                    01:00:00        192.168.1.50
dc2                   A          1          0                    01:00:00        192.168.1.51
Surface               A          1          10/24/2017 8:00:0... 00:20:00        192.168.1.141
server1                      A          1          10/19/2017 7:00:0... 00:20:00        192.168.1.200

但如果我运行附加命令

$alldns = Get-DnsServerResourceRecord -computername dns-server -ZoneName "domain.com" -RRType "A" | Select-Object -Property Hostname, RecordData, Timestamp

我得到了这个结果，ip消失了，并被DnsServerResourceRecordA取代。请指教。

pc2        DnsServerResourceRecordA   10/24/2017 6:00:00 PM
Gaming     DnsServerResourceRecordA   10/24/2017 6:00:00 PM
dc         DnsServerResourceRecordA
dc2        DnsServerResourceRecordA
Surface    DnsServerResourceRecordA   10/24/2017 8:00:00 PM
server1    DnsServerResourceRecordA   10/19/2017 7:00:00 PM

您可以通过为calculated property提取IPv4Address来完成此操作。在select-object中，您可以按以下方式使用@{Name='RecordData';Expression={$_.RecordData.IPv4Address}}而不仅仅"RecordData"

Get-DnsServerResourceRecord -computername dns-server -ZoneName "domain.com" -RRType "A" | select-object -Property Hostname,Timestamp, @{Name='RecordData';Expression={$_.RecordData.IPv4Address}}

或者

可以使用Recorddata提取

ExpandProperty。您必须在select-object中使用-ExpandProperty，其余（Hostname，Timestamp）可以使用-Property提取。您将在下方使用IPv4Address字段。

Get-DnsServerResourceRecord -computername dns-server -ZoneName "domain.com" -RRType "A" | select-object -ExpandProperty recorddata -Property Hostname,Timestamp

无论哪种方式，您都可以使用正确的IP地址替换DnsServerResourceRecordA ..

DNS记录数据以DnsServerResourceRecordA形式出现
