Actively scan explicitly authorized IPv4 targets to identify responsive hosts, open TCP ports, and likely service or OS fingerprints. Nmap and Masscan variants differ in port coverage and probe detail; observed responses do not establish vulnerability or prove a silent host is absent. This is active network-service discovery (T1046), not passive packet capture (T1040).
