Analysis results
Preparing the local analyzer.
Download the derived report with its measurement details. It does not include the original input file.
Prepare your evidence
Paste a BIND-style zone export and set its original zone name under Input details. The supported subset includes ordinary address, alias, nameserver, SOA, TXT, CAA, MX and SRV records. Includes, generated records and unsupported syntax are reported as unavailable. Review the exact record and line before changing an alias or TTL; delegated names can require separate checks.
Read the result and check the repair
Start with the observed failures and their evidence. Follow the next action for the affected item, then collect a new report using the same scope. Use the earlier report when this tool supports comparison. Differences between sites, collection windows or test conditions can prevent a meaningful comparison.
Local processing and limits
Files and pasted evidence are analyzed in your browser. They are not uploaded, added to the page address or saved in browser storage. Each input is limited to 2 MiB, with further limits shown by the analyzer. Closing or clearing this page removes its report from the page.
Exports contain the derived findings and measurement details. Review names, paths and text before sharing. A successful check describes the supplied evidence; it does not certify a whole website or replace a staging test.
