What you can build

  • Export Technitium DNS zones and compare record sets with a reviewed baseline, then list unexpected additions and removals.
  • Validate proposed DNS records for duplicate names, invalid TTLs, and conflicting values before an operator submits changes.
  • Run a maintained set of domain queries through Technitium and report blocklist, forwarding, and resolution outcomes.
  • Transform an approved CSV of record edits into documented Technitium API requests and a rollback manifest.
  • Compare Technitium DHCP lease exports with an address inventory and flag unexpected clients or duplicate assignments.

Try this prompt

Design a small internal DNS-change workflow using Technitium DNS Server’s documented HTTP API. Let an operator submit a proposed domain record change, validate the request, show a review before applying it, and record the outcome. Check the API documentation for supported actions rather than assuming endpoints. Preserve existing records, avoid destructive changes by default, and include setup notes and a focused test plan.

Get started

  1. Choose a deployment

    Follow the README installation guidance for Windows, Linux, macOS, Raspberry Pi, or Docker. Docker users can start from the linked compose example.

  2. Configure the server

    Use the admin web console for DNS and DHCP settings. For first-start Docker configuration, consult the linked environment-variable documentation.

  3. Automate or extend

    Use the HTTP API documentation to identify supported configuration actions, or follow the linked build instructions to build from source. Cross-platform builds require .NET 10.

License & notes

GPL-3.0The software is GPL-3.0; no software price is quoted here. Self-hosting requires infrastructure and administration, which may incur hardware, hosting, and bandwidth costs. Optional DNS forwarders may have their own terms or costs. If you distribute a modified covered version, GPL-3.0 obligations include providing corresponding source under the license terms; private use alone does not require publishing source.

  • DNS and DHCP deployment require suitable network configuration and operational knowledge; the server does not handle routing.
  • GPL-3.0 permits commercial use. Conveying modified covered software triggers license conditions, including corresponding-source obligations; private use alone does not require publishing source.
  • Self-hosting requires infrastructure and maintenance; optional forwarding services may have separate terms or costs.
