AS6111 FHIS

FHIS is registered to Adventist Health System/Sunbelt, Inc., the Florida-based non-profit hospital system that now operates as AdventHealth. The handle preserves the old name of its IT arm, Florida Hospital Information Services.

What it's used for

• Connectivity for a large hospital network's own operations: clinical and administrative systems across its hospitals and clinics, plus the corporate IT that supports them.
• The routed footprint is deliberately small: 512 addresses out of 204.156.112.0/23 and 204.156.113.0/24. That is normal for a healthcare organisation that keeps most of its estate internal and exposes very little directly.

Notable

• An enterprise / healthcare address, not an eyeball or hosting one. IPs here front a hospital system's own infrastructure; they are not consumer connections and are not sold to third parties.
• ARIN's registration for this ASN dates to November 1995, so this is a genuine mid-1990s allocation to an institution that was networking early by hospital standards.
• The registrant address in Orlando, Florida is the system's corporate home. Adventist Health System renamed itself AdventHealth in 2019, but the registry still carries the older entity name.
