Bias Analysis
Bias Types:
⚠️
windows_first
⚠️
powershell_heavy
⚠️
windows_tools
Summary:
The documentation demonstrates a Windows bias primarily in its examples and tool recommendations. PowerShell (Resolve-DnsName) is presented first and in more detail than Linux/Unix equivalents. Windows-specific tools and concepts (such as Group Policy, NRPT, and explicit references to Windows 10/11 clients) are mentioned without Linux parallels. The dig command is shown, but only as a secondary example, and there is no mention of Linux-native environments or tools like host or unbound. There are no Linux shell prompt examples, and the guidance assumes a Windows-centric audience.
Recommendations:
- Provide Linux/Unix shell examples (e.g., bash prompt, dig, host) alongside or before Windows/PowerShell examples.
- Mention Linux/Unix DNSSEC validation tools (e.g., unbound, bind, dnssec-trigger) and how to configure them.
- Balance references to Windows-specific features (like Group Policy and NRPT) with Linux equivalents (such as systemd-resolved, resolvconf, or dnssec-trigger).
- Clarify that dig is a cross-platform tool and provide installation instructions for both Windows and Linux.
- Include guidance or links for DNSSEC validation and troubleshooting on Linux systems.
- Use neutral language when describing client operating systems (e.g., 'Windows, Linux, and macOS clients...') where appropriate.
