dns-whois

Use local DNS and WHOIS tools for authorized domain, host, nameserver, mail, address, ASN, registration, and ownership triage.

Help First

Before constructing commands, use installed help or version output as the source of truth:

dig -h
nslookup -help
whois --help

Usage Rules

• Work only on in-scope domains, hosts, networks, or user-provided indicators.
• Record the exact queried identifier and query time when results support a finding.
• Prefer targeted record lookups over broad enumeration.
• Treat WHOIS, DNS, and registry data as time-sensitive intelligence that may be stale, proxied, incomplete, or privacy-protected.
• Cross-check important ownership, delegation, and resolution claims with independent DNS records or supporting evidence.
• Save large query batches and raw outputs to files rather than streaming them into the conversation.

Output

Report the queried identifier, command used, relevant records or ownership signals, confidence, time sensitivity, output paths, and any unresolved or conflicting evidence.
