Summary

Cincinnati Children's Hospital Medical Center

United States of America · AI-generated

hospital business healthcare enterprise

The AS handle CINCCHILDRENS is held by Cincinnati Children's Hospital Medical Center.

What it's used for

  • The address space carries internal hospital infrastructure, evidenced by the netnames CHMCC and CHMC and the reverse DNS record extranet.chmcc.org.
  • With 1536 IPv4 addresses across 2 prefixes and only 3 observed neighbours, the inventory represents a small, self-contained corporate estate rather than a transit or access network.

Notable

  • Both registrants for the announced prefixes are Cincinnati Children's Hospital Medical Center, matching the AS holder exactly.
  • The address inventory consists of two distinct IPv4 blocks: 205.142.196.0/22 and 204.152.48.0/23, with no IPv6 prefixes in the inventory.

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 1,779 prefixes, as published 2026-10-24. 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.
