Summary

The documentation page demonstrates a strong Windows bias: all command-line examples use PowerShell cmdlets, specifically those only available on Windows (e.g., Add-DnsServerConditionalForwarderZone, Resolve-DnsName, Test-NetConnection). There are no Linux or cross-platform DNS configuration examples, nor are Linux-native tools (such as dig, systemd-resolved, or BIND/named) mentioned. The prerequisites reference only the Azure PowerShell module. The narrative assumes Windows Server DNS as the default, with only a brief note that 'any DNS server' can be used, but no guidance for non-Windows environments.

Recommendations

Provide equivalent Linux/BSD examples for DNS forwarding configuration, such as using BIND/named or dnsmasq for conditional forwarding.
Include Linux-native command-line tools for DNS testing (e.g., dig, host, nslookup) alongside PowerShell examples.
Mention and link to documentation for configuring DNS forwarders on common Linux distributions.
Clarify in the prerequisites that Linux-based DNS servers are supported and provide relevant setup instructions.
Balance the order of presentation so that Windows and Linux approaches are given equal prominence, or provide a cross-platform section.
