I'm inquiring about how to delete Azure DNS.

Question

Due to the termination of the service contract, we would like to delete 20000 DNSs created for auto-scaling.
Is there a way to delete a domain containing a specific word in bulk?

EX) Delete all DNS with 'gne-'

Answer 1

Hi,

Before making changes to your DNS Zone, please Export your zone using the button at the top with down arrow icon. This will download a .txt file of your zone that you can import back in if necessary. After downloading, please open the file and make sure it has the contents of your zone.

Please see sample PowerShell code below to delete all A records that start with "gne-". You may run it in Azure CloudShell:

$recordSets = Get-AzDnsRecordSet -ResourceGroupName "uprism" -ZoneName "uprism.io" -RecordType A
$recordSets|ForEach-Object {if ($_.Name -like "gne-*") {Remove-AzDnsRecordSet -RecordSet $_ }}
