Summary
The documentation demonstrates a Windows bias by prioritizing Azure PowerShell and classic PowerShell examples, using Windows-specific tools and cmdlets, and omitting Linux-native command-line examples (such as Bash or shell scripting). While Azure CLI is cross-platform, the documentation does not provide explicit Linux shell or scripting guidance, nor does it mention Linux tools for DNS validation or troubleshooting. PowerShell examples are consistently presented first, reinforcing a Windows-centric workflow.
Recommendations
  • Add explicit Bash/shell command examples for all Azure CLI operations, demonstrating usage in a Linux environment.
  • Include Linux-native DNS troubleshooting tools (e.g., dig, host, nslookup) to validate reverse DNS records after configuration.
  • Alternate the order of examples (e.g., sometimes present Azure CLI before PowerShell) to avoid reinforcing a Windows-first workflow.
  • Clarify that Azure CLI commands are cross-platform and provide sample shell scripts for automation on Linux.
  • Where PowerShell is used for Cloud Services (which currently has no CLI support), acknowledge the lack of Linux-native options and suggest workarounds or feature requests.

Flagged Code Snippets

### Create a public IP address with reverse DNS

> [!NOTE]
> If the public IP address already exists in your subscription, see [Configure reverse DNS for a public IP address with an existing name](#configure-reverse-dns-for-a-public-ip-address-with-an-existing-name)

To create a new PublicIpAddress with the reverse DNS property already specified:

#### Azure PowerShell


### View reverse DNS for an existing public IP address

To view the configured reverse DNS value for an existing PublicIpAddress:

#### Azure PowerShell


### Remove reverse DNS from an existing public IP address

To remove a reverse DNS property from an existing PublicIpAddress:

#### Azure PowerShell


## Configure reverse DNS for Cloud Services

This section provides detailed instructions for how to configure reverse DNS for Cloud Services in the Classic deployment model, using Azure PowerShell. Configuring reverse DNS for Cloud Services isn't supported via the Azure portal, Azure classic CLI, or Azure CLI.

### Add reverse DNS to existing Cloud Services

To add a reverse DNS record to an existing Cloud Service:


### Remove reverse DNS from existing Cloud Services

To remove a reverse DNS property from an existing Cloud Service:
