Summary

Memorial Health Care Systems

United States of America · AI-generated

healthcare business internal

MEMORIAL-HEALTH-CARE-SYSTEMS is operated by Memorial Health Care Systems.

What it's used for

  • The address space carries internal corporate infrastructure, evidenced by the netname MHCS-9 assigned to the single announced prefix.
  • The AS announces 256 IPv4 addresses across 1 prefix with 2 observed neighbours, a ratio consistent with a small, self-contained internal network rather than a transit or access provider.
  • Traffic from this AS consists of internal data flows for a healthcare organization, supporting clinical systems, administrative functions, and facility operations.

Notable

  • The RDAP registrant Memorial Health Care Systems matches the AS holder name exactly.
  • The address inventory is minimal, consisting of a single /24 block, indicating a tightly scoped internal estate without external customer or subscriber allocation.

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: 446 networks and 1,852 prefixes, as published 2026-10-27. 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.
