Adds ~2,125 ASN-domain classifications carried out across four ~1,000-domain batches in a prior session that wasn't pushed before #748/#749 merged. The overlap with those merged batches is dropped — origin/master's classifications are kept as authoritative — and only the genuinely-new domains land here. 188 known-unknown rows are promoted out to the map for the same reason. Also updates bankonitusa.com from BankOnIT to Navanta and adds navanta.com as an alias after a spot check observed the operator's "now Navanta" rebrand banner. Two corroborating sources: the banner on bankonitusa.com itself (image-only `<a href="https://navanta.com/brand-launch-..."><img alt="Brand announcement"></a>`) and the rebrand explainer on navanta.com ("Why We Became Navanta", "MyBankonIT has been rebranded to MyBPC"). The MMDB still names the pre-rebrand entity (BankOnIT, L.L.C.) — typical years-of-lag pattern.

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.
