AS784

AS784 is a currently unrouted autonomous system registered to the Henry M. Jackson Foundation for the Advancement of Military Medicine (HJF), a Bethesda, Maryland-based nonprofit that administers DoD-affiliated military medical research. ARIN's RDAP record shows the ASN was first registered on 1990-11-20 and last changed 2025-02-20, but no routing source consulted shows it announcing any prefixes today.

HJF is a 501(c)(3) nonprofit created by an act of Congress in May 1983 and renamed that September for Senator Henry M. "Scoop" Jackson. It administers roughly 700 research grants and contracts and provides internal IT and HPC services supporting DoD-affiliated military-medicine research, but no HJF-official page ties AS784 specifically to that mission.

Historically, AS784 originated a single IPv4 prefix, 144.83.0.0/16, first seen 2014-10-05 and last seen 2026-01-05; it has not been visible in the global routing table since. CAIDA shows an AS rank of 79,459, a singleton customer cone (0 prefixes, 0 addresses), and zero degree across customer, peer, and provider relationships — all consistent with a dormant, enterprise-style ASN rather than an active network operator.

No PeeringDB record exists for AS784 (confirmed 404), and no peering policy is published, so peering posture and network type are recorded as Unknown/Likely rather than assumed. RPKI is not assessable for AS784: it announces no prefixes at check time (0 v4/0 v6, 0 observed neighbours), so there is no live route to validate against a ROA.

Operator

The Henry M. Jackson Foundation for the Advancement of Military Medicine, Inc. (HJF) (nonprofit; ARIN handle HJFNET-AS, Bethesda, MD) [Confirmed] — ARIN RDAP (rdap.arin.net/registry/autnum/784), hjf.org/about

Country / RIR

US, ARIN [Confirmed] — ARIN RDAP autnum

Allocated

1990-11-20 (ARIN RDAP top-level autnum registration event); last changed 2025-02-20 [Confirmed] — ARIN RDAP autnum top-level events; corroborated by bgp.tools ("Registered: November 20, 1990")

Org status

active 501(c)(3) nonprofit, founded May 1983 by act of Congress, renamed Sept 1983 for Sen. Henry M. "Scoop" Jackson; HQ Bethesda, MD; ARIN registration status "active" though the NOC POC (HJFNO-ARIN) is flagged unvalidated since 2026-02-19 [Confirmed] — hjf.org/about, ARIN RDAP

Security/abuse context (NEUTRAL, DATED)

no notable public abuse signal found as of 2026-08-01 — not present in the Conticop/bad-asn-list hosting-abuse blocklist (checked directly); Spamhaus's own site could not be queried directly (403 blocked) so its listing status is unconfirmed either way; bgp.he.net's "announces bogons" notice is uncorroborated by bgp.tools and treated as unverified [Confirmed for blocklist absence; Unknown for Spamhaus specifically] — github.com/Conticop/bad-asn-list, bgp.he.net/AS784

Network & routing

Network type

Unknown/Likely enterprise-institutional network — no PeeringDB record exists (404), and HJF's own site describes only internal IT/HPC services, not a carrier or ISP role [Likely] — peeringdb.com/asn/784, hjf.org/it-services

Size

currently 0 IPv4 prefixes / 0 IPv4 addresses announced (historically 1: 144.83.0.0/16, first seen 2014-10-05, last seen 2026-01-05); 0 IPv6 prefixes; customer cone = 1 ASN (itself), 0 prefixes, 0 addresses [Confirmed] — RIPEstat, CAIDA AS Rank, bgp.he.net, bgp.tools (2026-08)

Routing/peering

NOT currently announced — 0 RIS peers seeing it (0/328 v4, 0/322 v6); CAIDA degree total 0 (customer 0, peer 0, provider 0); no current peers/upstreams visible. bgp.he.net lists AS6461 (Zayo Bandwidth) and AS33657 (Comcast) as historical (not current) upstream/peer associations from when the prefix was last routed [Confirmed for current state; Likely for historical association] — stat.ripe.net/data/routing-status, api.asrank.caida.org, bgp.he.net/AS784, bgp.tools/as/784

RPKI

not assessable — AS784 announces no prefixes at check time (0 v4/0 v6, 0 observed neighbours), so there is no live route to validate against a ROA [Confirmed] — stat.ripe.net/data/routing-status/data.json?resource=784, stat.ripe.net/data/as-overview/data.json?resource=784

Notable usage

Unknown from operator-official sources — no first-party HJF page ties AS784 to a specific technical function; contextually HJF manages 700+ DoD-affiliated military-medicine research grants and IT/HPC services, but this isn't directly documented as tied to AS784

[Unknown] — hjf.org/it-services, hjf.org/about

Related ASNs

none confirmed as commonly-operated sibling ASNs; AS6461 (Zayo) and AS33657 (Comcast) appear only as historical upstream/peer associations, not affiliated ASNs [Likely] — bgp.he.net/AS784

Analyst note

AS784 is RIR-active but operationally dormant — registered to a DoD-affiliated military-medicine nonprofit, not a network operator; no PeeringDB presence and only one historical /16 announcement, unrouted since January 2026.
