Which tool is used to perform reverse DNS lookups on a target host?

• A. DNSdumpster
• B. tracert
• C. Domain Dossier
• D. DNSRecon

Answer: (D)

Reverse DNS lookups map an IP address back to a hostname by querying PTR records in the DNS. In offensive security work, you often want to quickly turn a list of IPs into hostnames to understand the target’s exposed infrastructure. DNSRecon is designed for DNS enumeration and includes capabilities to perform reverse DNS (PTR) lookups across IP ranges, revealing the hostnames associated with those addresses. It automates the process of querying reverse records and integrates this data with other DNS information, making it a robust choice for discovering how IPs map to identifiable hosts. The other options don’t fit as well because they’re not focused on automated reverse DNS enumeration: tracert traces the network path to a host and is not a reverse DNS tool; DNSdumpster and Domain Dossier are OSINT services that gather DNS data but aren’t specialized, scriptable tools for performing comprehensive reverse DNS lookups across ranges in a penetration-testing workflow.
