About this network

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-205-221 associated 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.
