This article provides a practical, step-by-step introduction to DNSDB and Security Information Exchange (SIE) file formats and tooling: it explains MTBL/DNSTABLE, NMSG, and JSON Lines formats, how to install and use mtbl/dnstable/libnmsg/sie-nmsg utilities, options for compression and conversion (including example commands and performance numbers), and a worked example of capturing SIE channel data, filtering RRtypes, converting between JSONL/NMSG/MTBL, and querying with dnstable_lookup.
