Summary
Great River Health Systems
healthcare business internal iowa
GREATRIVERHEALTHSYSTEMS is operated by Great River Health Systems, Inc.
What it's used for
- The space carries internal corporate traffic for a regional healthcare system, evidenced by the registrant netname
ICN-GW-205-221associated with Iowa Communications Network. - 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 for the announced prefix is Iowa Communications Network, which differs from the AS holder, suggesting the address space is leased or provisioned via the regional telecom carrier.
- The address inventory consists of a single /24 block, consistent with a site-specific or internal corporate estate rather than a distributed service network.

Internet exchanges
No exchange port on file. Many exchanges publish no participant list, so this is not proof of absence.
Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-22, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

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: 442 networks and 1,779 prefixes, as published 2026-10-23. 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.
