EXPLAINABLE RULES

Build the filter

Group logic

Group Join Rule Value

Safe regex rejects backreferences, lookarounds, control escapes, long patterns, and suspicious nested quantifiers. Matching runs in a disposable worker with a hard timeout.

No rules: all valid rows are included.

The table renders the first 500 matching rows for responsiveness. Exports include every included row unless you select specific rows. RDAP is off by default; its two-step lookup sends only the selected domain to the authoritative registry.
