Summary

Bozeman Deaconess Health Services

United States of America · AI-generated

healthcare business static single-site

BDHS-AS is held by Bozeman Deaconess Health Services.

What it's used for

  • The space carries static connectivity for a healthcare facility, evidenced by the netname BDHS and reverse DNS entries pointing to dia.static.qwest.net.
  • The AS announces 256 IPv4 addresses within a single /24 prefix (205.166.158.0/24) and maintains one observed neighbour, indicating a small, isolated site network rather than a transit or large-scale access provider.
  • Traffic from this AS consists of internal hospital systems, administrative endpoints, and clinical infrastructure for the 125-bed Bozeman Health Deaconess Regional Medical Center in Bozeman, Montana.

Notable

  • The RDAP registrant Bozeman Deaconess Health Services matches the AS holder and the netname BDHS, confirming consistent ownership of the address space.
  • The address inventory is a single contiguous /24 block, typical for a dedicated corporate or institutional site requiring a fixed range of public IP addresses for services and remote access.

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: 443 networks and 1,784 prefixes, as published 2026-10-19. 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.
