United States of America · AI-generated

hospital business us small

MURRAY-CALLOWAY-COUNTY-HOSPITAL is the autonomous system for Murray-Calloway County Hospital, a non-profit community hospital in Murray, Kentucky.

What it's used for

  • The space carries the hospital's internal network infrastructure, identified by the netname MURRAY-CALLOWAY-COUNTY-HOSPITAL and registrant Murray-Calloway County Hospital.
  • The AS announces a single IPv4 prefix, 192.40.157.0/24, comprising 256 addresses, with 0 IPv6 prefixes.
  • With only 2 observed neighbours, the low neighbour count relative to the address space indicates a small, self-contained site network rather than a transit or large access provider.

Notable

  • The RDAP registrant Murray-Calloway County Hospital matches the AS handle and the known identity of the operator.
  • The address inventory consists of a single /24 block, which is typical for a small corporate or institutional site requiring a modest amount of public IP space.

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 1,778 prefixes, as published 2026-10-20. 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.
