Reads email messages (alignment, the Received chain, and where it really came from), lists of IPs or domains, CSV and JSON exports, and metadata from images, PDFs and Office documents.

Dry-run plan first. Nothing scrapes until you confirm a run on the next screen.

Quick reputation check

One host against public blocklists and malware feeds (Spamhaus, OpenPhish, abuse.ch and more) — or offline numbering-plan validation for a phone number. Not a full investigation — for that, use the search box above.

Absence of a listing is not proof the host is safe. A valid phone format is not proof of who answers or whether the number is spam.
