Summary

Community Health Network

United States of America · AI-generated

healthcare business internal us

COMMUNITY-HEALTH-NETWORK is operated by Community Health Network, a hospital system based in Indianapolis.

What it's used for

  • The address space carries internal hospital infrastructure, evidenced by registrants like "Community Hospital of Indianapolis" and "Community Hospitals, Indianapolis; IT Security" across all prefixes.
  • The AS announces 2,816 IPv4 addresses across 6 prefixes with only 2 observed neighbours, indicating a small, self-contained corporate network rather than a transit or access provider.

Notable

  • All six announced prefixes share the netname COMMUNITY-HEALTH-NETWORK and are registered to either "Community Hospital of Indianapolis" or "Community Hospitals, Indianapolis; IT Security", confirming consistent ownership.
  • The inventory consists of a mix of /22, /23, and /24 blocks within the 204.108.48.0/20 range and a single /24 in 198.140.195.0/24, reflecting a segmented internal estate.

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: 454 networks and 1,852 prefixes, as published 2026-11-08. 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.
