Classify reverse DNS map: next 5000 unmapped MMDB ASN domains (#758)

Browse Source

Auto-classification rate jumped back to 50% (2502/4999) from 36.5% in
batch 8 — this slice happens to contain a higher proportion of small ISPs
with conventional homepages, lifting the regex hit rate.

- 2,502 added to base_reverse_dns_map.csv (ISP 2,065, Web Host 133,
  Education 96, Finance 67, MSP 60, Government 58, Healthcare 23).
- 2,496 added to known_unknown_base_reverse_dns.txt.

ASN-domain coverage of the bundled IPinfo Lite MMDB after this batch:
  - by domain count:  19,154 / 63,993  (29.93%, up from 26.02%)
  - by IPv4 weight:   98.18%           (up from 98.09%)

Same classifier as batches 5-8 (no new code).
