Dns Reconnaissance — CompTIA PenTest+ (PT0-002) Practice Questions

DNS reconnaissance is the process of systematically querying DNS infrastructure to map a target's hosts, subdomains, mail servers, and associated IP ranges. On the PT0-002 exam, this concept appears in the reconnaissance and information gathering domain, where candidates must demonstrate knowledge of techniques such as forward and reverse lookups, subdomain brute-forcing, and DNS record analysis. The value of DNS reconnaissance is that it often requires no special access and can reveal assets the organization does not realize are publicly visible. Testers use tools like nslookup, dig, and automated subdomain enumeration utilities to perform this work.
