Updates to Domainname API, (Wed, Nov 5th)

SANS ISC has updated its "recent domains" service, adding an hourly updated static feed (domaindata.json.gz) and refining the API to support filtered, paginated queries and multiple formats (e.g., JSON). The post provides example endpoints and parameters, notes that Certificate Transparency logs may surface older domains as "new," outlines limited retention for historical daily files, and advises using the data to enrich logs rather than as a blocklist.
