Summary:
The documentation page demonstrates a Windows bias by prioritizing Windows tools and patterns. PowerShell (Resolve-DnsName) is presented first and in more detail, with multiple examples, while Linux/Unix-native tools (dig) are mentioned but not explained as thoroughly. The documentation references Windows-specific features (such as Group Policy and NRPT) without mentioning Linux equivalents or validation methods. There are no explicit Linux command-line examples (e.g., bash shell usage), and the guidance assumes familiarity with Windows environments.
Recommendations:
- Provide Linux/Unix command-line examples (e.g., using dig in bash or sh, with sample output).
- Present dig (the cross-platform tool) examples before or alongside PowerShell examples to avoid Windows-first ordering.
- Mention Linux/Unix DNSSEC validation methods and tools (e.g., unbound, bind, systemd-resolved) where Windows Group Policy and NRPT are discussed.
- Clarify that dig is available by default on most Linux distributions, and provide installation instructions for both Windows and Linux if needed.
- Balance the number and detail of examples between Windows and Linux environments.
- Reference Linux documentation or man pages for DNSSEC validation and troubleshooting.
