Unclassified ARIN
Summary
BRFHH Shreveport, L.L.C. (Ochsner LSU Health Shreveport)
enterprise legacy
AS11324 is held by BRFHH Shreveport, L.L.C. — the hospital-holding entity created by the Biomedical Research Foundation of Northwest Louisiana when it took over the LSU teaching hospital in Shreveport under Louisiana's 2013 charity-hospital privatisation. The hospital has since run as Ochsner LSU Health Shreveport, following the 2018 partnership between LSU Health Shreveport and Ochsner Health, and the netname on the routed space says so directly: OLHS-PUBLIC-01.
What it's used for
An academic medical centre's public edge. RIS sees 3 IPv4 prefixes, 768 addresses, no IPv6 and a single observed neighbour — three /24s (104.153.252.0/24, 104.153.254.0/24, 104.153.255.0/24), all registered to BRFHH Shreveport itself, all reached through one upstream. Registrant and origin agree on every prefix; there is no third-party registrant, no second RIR, nothing that resembles leased or brokered address space.
Notable
The netname is the most informative single field in the pack. OLHS-PUBLIC-01 — Ochsner LSU Health Shreveport, public — states the block's purpose: the internet-facing tier of the hospital, held apart from the clinical estate that lives on private address space behind it. That is why the routed footprint is three /24s for an institution with a hospital, a medical school affiliation and a research programme attached. The routed space measures the edge, not the enterprise.
One neighbour and 768 addresses is unambiguous as a role signal. This network sells no connectivity and transits nobody; it exists so that a hospital can hold its own portable addresses for VPN endpoints, remote clinician access, payer and referral interfaces, and its public web presence.

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: 449 networks and 1,846 prefixes, as published 2026-11-03. 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.
