additional context — IP + user-agent lookups
lookups that complement a dossier — useful when investigating a finding, but not part of the dossier engine itself.
- IP lookup — geolocation, ASN, ISP for any IP address surfaced by the DNS or redirect sections.
- user-agent parser — the browser/OS/device the request came from.
- single-record DNS lookup — drill into one record type at a time.
