Summary

Cambia Health Solutions

United States of America · AI-generated

healthcare business enterprise

The AS handle CAMBIAHEALTH is held by Cambia Health Solutions, Inc.

What it's used for

  • The address space carries internal corporate infrastructure for a healthcare provider, as indicated by the consistent netname CAMBIAHEALTH and registrant Cambia Health Solutions, Inc. across all listed prefixes.
  • The AS announces 11008 IPv4 addresses across 14 prefixes with only 3 observed neighbours, a ratio that implies an internal corporate estate with site-by-site segmentation rather than an access or transit network.

Notable

  • All registrants for the largest prefixes agree with the announcer, consistently listing Cambia Health Solutions, Inc. as the registrant.
  • The address inventory is finely subdivided into multiple /24 and /22 blocks within the 161.208.0.0/20 range, alongside two isolated /24 blocks in different ranges, reflecting a segmented internal network structure.

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: 448 networks and 1,849 prefixes, as published 2026-10-30. 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.
