Summary

Meritus Medical Center

United States of America · AI-generated

healthcare business internal

MERITUSHEALTH is the autonomous system for Meritus Medical Center, Inc.

What it's used for

  • The space carries internal hospital infrastructure, evidenced by the netname MMC and registrant Meritus Medical Center, Inc.
  • The AS announces 512 IPv4 addresses across 1 prefix with 2 observed neighbours, indicating a small, self-contained internal network rather than a transit or access provider
  • Traffic consists of internal data for an acute care hospital facility, including clinical systems, administrative networks, and patient care infrastructure

Notable

  • The registrant Meritus Medical Center, Inc. matches the AS holder and netname MMC
  • The address inventory consists of a single /23 block (198.49.138.0/23), representing a compact, dedicated allocation for the hospital's operations

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 1,783 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.
