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