About this utility
How to use Offline DNS Record Analyzer
Parse BIND-style A, AAAA, CNAME, MX, TXT, SPF, DMARC, DKIM, CAA, NS, SOA, SRV, and PTR records without DNS queries.
What to provide
Paste complete BIND-style record lines. Comments beginning with semicolons are ignored outside quoted strings.
- Paste, type, or drag and drop a supported text file into the input area.
- Review the input and the clearly labeled output behavior.
- Select “Run tool” or press Ctrl/Command + Enter, then copy, download, or move the result back into the first input for another pass.
What the result means
A record table plus offline SPF, DMARC, and CAA diagnostics.
Privacy and safety
This utility is loaded as browser code and processes your input only in this tab. OmniCastConverter has no upload endpoint and never stores your content, filenames, tokens, or secrets. Generated markup and code are shown as inert text and are never executed.
Limitations
- Everything is processed in this browser tab. Input, filenames, keys, and output are never uploaded or saved. It never resolves records, validates DNSSEC, downloads DKIM keys, or checks propagation.
