Summary

Cleveland Clinic Foundation

United States of America · AI-generated

healthcare business enterprise

The AS handle CCF-NETWORK is held by Cleveland Clinic Foundation.

What it's used for

  • The address space carries internal corporate infrastructure for a major academic medical center, evidenced by netnames CCFNET1 and MERIDIA associated with Cleveland Clinic Foundation and Meridia Health System.
  • The AS announces 131,840 IPv4 addresses across 27 prefixes while maintaining only 3 observed neighbours, a ratio that indicates an internal corporate estate with site-by-site segmentation rather than an access or transit network.

Notable

  • Registrants align with the announcer, showing Cleveland Clinic Foundation for the 139.137.0.0/17 block and Meridia Health System for the 167.90.0.0/17 block, reflecting the integration of acquired health systems into the foundation's network.
  • The inventory consists of two large /17 blocks subdivided into numerous smaller prefixes, creating a finely segmented address space typical of a large multi-site organization.

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 1,782 prefixes, as published 2026-10-16. 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.
