Summary

Sutter Health

United States of America · AI-generated

healthcare business enterprise california

SUTTERHEALTH is operated by Sutter Health.

What it's used for

  • The address space carries internal corporate infrastructure, evidenced by netnames SUTTER and SUTTER-HEALTH registered to Sutter Health.
  • The AS announces 6,656 IPv4 addresses across 4 prefixes with only 2 observed neighbours, indicating a small, self-contained internal network rather than a transit or access provider.
  • Traffic from this AS consists of internal communications, clinical systems, and administrative endpoints for a not-for-profit health delivery system operating hospitals and clinics across California.

Notable

  • All registrants for the announced prefixes are Sutter Health, matching the AS holder.
  • The address inventory is finely subdivided into four distinct blocks, consistent with site-by-site segmentation for a large multi-facility 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: 452 networks and 1,853 prefixes, as published 2026-11-05. 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.
