DNS Zone File Validator

Validate common BIND-style DNS zone files for syntax problems, record consistency, and deployment mistakes before loading them on a DNS server.

Browser-side validation
Privacy: pasted zone content and locally selected files are processed in your browser by this tool. This plugin does not intentionally upload or store zone data on the website server.

Zone input

Paste a zone file or load a local .zone, .db, or .txt file.

No file selected

How to use

  1. Paste a BIND-style zone file, or choose a local text zone file.
  2. Select strict checks if you want consistency warnings such as CNAME conflicts and missing apex records.
  3. Click Validate zone.
  4. Correct errors first, then review warnings and informational findings.
  5. Before production, validate the final file with the DNS server's native tool, for example named-checkzone for BIND.
