Summary

SwedishAmerican Health System

United States of America · AI-generated

healthcare business enterprise

The AS handle SAHS is held by SwedishAmerican Health System Corporation.

What it's used for

  • The address space carries internal corporate infrastructure, evidenced by the netname SAHS-2 and the registrant SWEDISHAMERICAN HEALTH SYSTEM CORPORATION.
  • The AS announces 256 IPv4 addresses across 1 prefix with 2 observed neighbours, indicating a small, self-contained internal network rather than a transit or access provider.

Notable

  • The registrant SWEDISHAMERICAN HEALTH SYSTEM CORPORATION matches the AS holder, confirming direct ownership of the address space.
  • The operator rebranded as UW Health, a name change reflected in secondary sources but not yet in the registry data.
  • The inventory consists of a single /24 block (209.94.50.0/24), representing a finely subdivided internal estate typical of a large healthcare organization.

Reputation

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: 447 networks and 1,843 prefixes, as published 2026-11-01. 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.
