Summary

Bronson Healthcare Group

United States of America · AI-generated

healthcare business internal

BRONSON-HEALTHCARE-GROUP-INC is held by Bronson Healthcare Group, Inc.

What it's used for

  • The space carries internal corporate traffic for a healthcare system, evidenced by the netname MICH-764 and registrant Bronson Methodist Hospital.
  • The AS announces 512 IPv4 addresses within a single prefix (198.108.140.0/23) and maintains 2 observed neighbours, a ratio consistent with a small, self-contained enterprise network rather than a transit or access provider.
  • Traffic from this AS consists of office workers, medical staff, and clinical systems operating across Bronson Healthcare's facilities in southwest Michigan and Northern Indiana.

Notable

  • The RDAP registrant Bronson Methodist Hospital aligns with the AS holder Bronson Healthcare Group, Inc., confirming the address space is owned by the same corporate entity.
  • The address inventory is compact, consisting of a single /23 block, which reflects the limited scale of the organization's direct internet presence.

Reputation

Classification and threat

Unclassified Not in the curated lists. Most of the ~80,000 allocated ASNs are not.

Spamhaus DROP

Not on ASN-DROP The network as a whole is not listed.

No DROP prefixes None of its announced space is on the DROP prefix list.

Spamhaus DROP ("Don't Route Or Peer") lists space and networks run by, or hijacked for, spam and cybercrime operations: 442 networks and 1,779 prefixes, as published 2026-10-23. A short, high-confidence list, so a match is worth taking seriously, and absence from it says little on its own.

FBI IC3

No IC3 indicators Nothing from the FBI IC3 feed.

IC3 threat data is alpha. Absence of an indicator is not evidence of good behaviour, only of absence from this one feed.
