Which online services are listed as examples of DNS lookup resources?

• A. DNSdumpster.com, Bluto, and Domain Dossier
• B. DNSRecon, DNSdumpster, and Reverse IP Domain Check
• C. Tracert, Tcptraceroute, Ping
• D. TXT, HINFO, PTR

Answer: (A)

Online DNS lookup resources are web-based tools you can use to query DNS records and map a domain’s footprint without installing software. The trio DNSdumpster.com, Bluto, and Domain Dossier fits this because each is a publicly accessible service that performs DNS lookup and footprinting tasks, showing records, subdomains, and related domain information. DNSdumpster is widely used for collecting DNS records and visualizing how a domain is configured; Domain Dossier compiles data about a domain, including DNS and ownership details; Bluto is another web-based DNS lookup resource that provides similar domain information. The other options mix different things: one line includes a command-line tool and online lookups that aren’t purely web-based DNS lookup resources, and the remaining options point to actual DNS record types rather than services. So the listed online services are the best examples of DNS lookup resources.
