New DNSDB -V summarize option: Sometimes "Less" Is "More"

This article documents the `dnsdbq -V summarize` feature of Farsight's DNSDB client, explaining that the summarize verb returns aggregated first-seen/last-seen times and summed counts for only the results that would have been returned by a normal query (respecting the result limit), provides examples (including `www.mit.edu` and `*.uber.com`), notes zone-file vs sensor-derived timestamps, and discusses quota and usage considerations.
