Continued the MMDB ASN-domain coverage walk into the 18k–14k IPv4-weight band. Added 941 new map entries and 59 new known-unknown entries from the top 1,000 unmapped candidates. ASN-domain coverage by IPv4 weight: 96.0% → 96.5%. ASN-domain coverage by domain count: 9.5% → 11.0%. Composition: ~50 universities and government / state agencies (HMRC, SSA, DHS, DOJ, BART, Pittsburgh, Charlotte, NY courts, Bank of Canada, MTA, gov.si, gov.ru, KAUST, Sharif University, Karolinska Institutet, IIT, KTH, etc.), ~70 globally-known brands (Nvidia, AMD, BMW, Mastercard, Nasdaq, NetApp, Allianz, Honeywell, JPMorgan, Goldman Sachs, Mitel, Arista, Take-Two, Universal Music, Disney Go, Fox, Nike, Cigna, Aetna, Humana, AbbVie, Mitsubishi Electric, Saint-Gobain, Reliance Industries, Hyundai Autoever, Square Enix, NEXON, Riot Games, Mahidol University, Hong Kong HSBC, Standard Chartered, etc.), and the long tail of regional ISPs / hosters / MSPs / data center operators classified via MMDB as_name + homepage corroboration. 59 added to known-unknown where the two-corroborating-sources bar wasn't met. Files remain disjoint per the workflow guardrail. sortlists.py validates clean (types, sort, dedupe). CRLF preserved.

parsedmarc
parsedmarc is a Python module and CLI utility for parsing DMARC
reports. When used with Elasticsearch and Kibana (or Splunk), it works
as a self-hosted open-source alternative to commercial DMARC report
processing services such as Agari Brand Protection, Dmarcian, OnDMARC,
ProofPoint Email Fraud Defense, and Valimail.
Note
Domain-based Message Authentication, Reporting, and Conformance (DMARC) is an email authentication protocol.
