Retrieve "same as parent folder" A record using Get-DnsServerResourceRecord

  • 772

I am trying to retrieve a single A Record from a zone. Here's the Powershell command I am using(showing only relevant columns)

Get-DnsServerResourceRecord -zonename search.contoso.com -computername g-dc03 -RRType A

HostName                  RecordType RecordData
--------                  ---------- ----------
@                         A          192.23.12.40
stg                       A          172.25.77.56

In the "DNS Manager" GUI, I see the first record as "same as parent folder". I would like to retrieve just this one record, not the stg record. I tried and failed with the following commands, all of them result in same 2 rows.

Get-DnsServerResourceRecord -zonename search.contoso.com -computername g-dc03 -RRType A -Name "."
Get-DnsServerResourceRecord -zonename search.contoso.com -computername g-dc03 -RRType A -Name '.'

Get-DnsServerResourceRecord -zonename search.contoso.com -computername g-dc03 -RRType A -Name search.contoso.com

HostName                  RecordType RecordData
--------                  ---------- ----------
search.contoso.com        A          192.23.12.40
stg                       A          172.25.77.56

    If I understand you correctly, you want something like this

    Get-DnsServerResourceRecord -ZoneName search.contoso.com -computername w-dc03 -RRType A | ? {$_.Hostname -like '@'}

    You can replace @ with any search term, or you can change the -like '@' to -notlike 'stg' to list all A records other then the stg record

    If that isn't what you are looking for please post a comment and I will amend accordingly

    EDIT: Doing the same without where

    Get-DnsServerResourceRecord -ZoneName search.contoso.com -computername w-dc03 -RRType A >> output.txt

Select-String -Path .\output.txt -Pattern "(@|HostName)" |select line
