  title: Shodan Reverse DNS to Host Info
  summary: Reverse-resolve an IP to its hostnames, then pull the full host record.
  description: >-
    An IP-first reconnaissance pattern. The workflow performs a reverse DNS
    lookup to discover the hostnames associated with an IP, then retrieves the
    full Shodan host record for that IP including every indexed service. Every
    step spells out its request inline so the flow can be read and executed
    without opening the underlying OpenAPI description.
