Going From A Domain Name to IP Address in DNSDB: Some "Pro Tips" To Keep In Mind

This guide explains how to use Farsight DNSDB (and the dnsdbq client) to map domain names to IPs, including how DNSDB returns different record types by default, how to time-fence historical results, how to chase CNAME chains to obtain final A/AAAA records, how single DNS answers can contain multiple IPs, and how large numbers of unique responses can be derived from relatively small IP pools; it is an operational/tutorial piece rather than a security incident report.
