During reconnaissance, the goal is to gather publicly available data that ties a domain to an organization and reveals the infrastructure behind it. Information about ownership and IP addresses—found in WHOIS records, domain registries, and IP allocation databases—lets you identify who controls the domain and which IP blocks are associated with it. That visibility often also uncovers server details through DNS records, hosting providers, and related infrastructure, giving a clear picture of the domains and the servers responding to them. The other options rely on data that is typically private or inaccessible during initial, non-intrusive recon (user passwords, encryption keys) or internal materials (diagrams) that aren’t exposed publicly, so they don’t help with mapping domain ownership, IP ranges, and server setup.
