Windows

• Download the NSD binary: Visit the NSD project website and download the appropriate binary for Windows.
• Extract the files: Extract the downloaded archive to a directory of your choice.
• Configure NSD: Create a configuration file (e.g., nsd.conf) and configure the necessary settings.
• Run NSD: Run the nsd executable from the command line.

Additional Considerations:

• Firewall rules: Ensure that your firewall allows incoming and outgoing traffic on port 53 (the default DNS port).
• DNS zone files: Create DNS zone files for your domains and configure NSD to use them.
• DNSSEC: If you want to enable DNSSEC, you’ll need to generate keys and configure NSD accordingly.
• DNSSEC validation: Configure NSD to validate DNSSEC signatures received from other DNS servers.

For more detailed instructions and configuration options, refer to the NSD documentation: https://www.nlnetlabs.nl/projects/nsd/about/ By following these steps, you can successfully install NSD and start using it to manage your DNS zones and provide DNS services.
