TDQS
Scored across 7 tools
Each tool targets a specific and distinct DNS record type or operation (individual records, combined query, subdomain search). No overlap or ambiguity.
Most tools follow the 'get_*_records' pattern, but 'query_domain' and 'search_subdomains' break the pattern. Still, all names are descriptive and predictable.
7 tools is an ideal size for a DNS lookup server—covers essential record types and common operations without being overwhelming.
Covers core DNS records (A, CNAME, MX, NS, TXT) plus subdomains, but lacks some common types like AAAA, SOA, or SRV. Minor gap but main functionality is complete.
