Diff Output

RFC Normalization Engine

Parses standard BIND syntax directives. Unifies implicit origins and matches lowercase formatting matrices automatically.

Time-to-Live (TTL) Conversion

Converts relative intervals (e.g., 1h, 1d) into strict second integers to prevent cosmetic configuration drift anomalies.

100% Client-Side Privacy

No zone data leaves your workstation. String-matching matrices run entirely inside your browser.
