AS384

AS384 is a legacy autonomous system number registered under ARIN to Air Force Systems Networking, a U.S. Department of the Air Force / Department of Defense network entity whose registration and abuse handling are administered by DISA-Columbus (the Defense Information Systems Agency). A structural quirk shapes every fact here: ARIN's RDAP autnum lookup for the number 384 resolves not to a discrete per-ASN object but to a range-level record — handle "AS379", name "AFCONC-BLOCK1-AS", covering startAutnum 379 through endAutnum 508. Individual ASNs in that legacy block were bulk-registered to Air Force Systems Networking and do not each carry separate registry objects, so the registrant identity, address, and dates below are inherited from that block record and independently corroborated by ipip.net, bgp.he.net, and bgp.tools. AS384 itself does show ASN-specific routing data: it announces a single IPv4 prefix, 134.165.4.0/24 (256 addresses), no IPv6, and appears with near-universal RIS visibility (322 of 323 peers) and one observed upstream/peer, AS27064 (the DoD Network Information Center). The block's top-level ARIN registration event dates to 1989-08-04 (last changed 2008-06-06). No AS384-specific abuse, hijack, or route-leak signal was found across Spamhaus, abuse.ch, AbuseIPDB, or NANOG archives as of 2026-07-02 — a neutral, dated null consistent with a small, single-prefix, DISA-managed federal stub network rather than a public transit or hosting operator.

Operator

Air Force Systems Networking (U.S. Department of the Air Force / DoD; ARIN registrant handle 7ESG; registration administered by DISA-Columbus) [Confirmed] — ARIN RDAP autnum/384, bgp.tools/as/384, bgp.he.net/AS384

Country / RIR

US, ARIN [Confirmed] — RIPEstat abuse-contact-finder (authoritative_rir: arin)

Allocated

1989-08-04 (ARIN RDAP autnum TOP-LEVEL registration event for the AFCONC-BLOCK1-AS block AS379–508 containing AS384; this is the first-party RIR allocation fact, NOT an IEEE date); last changed 2008-06-06 [Confirmed] — ARIN RDAP autnum top-level events[]

Org status

active. ARIN RDAP status for the containing block is "active"; bgp.tools reports AS384 as "Active, Allocated under ARIN"; RIPEstat announced=true [Confirmed] — ARIN RDAP autnum/384, bgp.tools/as/384

Contacts

disa.columbus.ns.mbx.arin-registrations@mail.mil (abuse/admin/tech, DISA-Columbus, 300 North James Road, Whitehall, OH 43213); registrant HQ Maxwell AFB, AL [Confirmed] — RIPEstat abuse-contact-finder, ARIN RDAP autnum/384

Security/abuse context (NEUTRAL, DATED)

no notable public abuse signal found as of 2026-07-02 — not in Spamhaus, abuse.ch, AbuseIPDB, or NANOG archives; a Scamalytics page for the broader "Air Force Systems Networking" org umbrella exists but returned HTTP 403 and would reflect the org's full multi-ASN portfolio, not AS384's single /24

Network & routing

Network type

U.S. federal government / military network, part of the DoD Information Network (DODIN); range-level record "AFCONC-BLOCK1-AS", registrant address 501 East Moore Dr., Bldg 884 Rm 1100, Gunther Annex, Maxwell AFB, AL 36114 [Confirmed] — ARIN RDAP autnum/384, whois.ipip.net/AS384

Size

announces 1 IPv4 prefix (134.165.4.0/24, 256 addresses) and 0 IPv6 prefixes [Confirmed] — RIPEstat routing-status / bgp.he.net / bgp.tools (2026-07)

Routing/peering

134.165.4.0/24 seen by 322 of 323 RIS v4 peers (near-universal), 0 of 322 v6 peers; 1 observed BGP neighbour — upstream/peer AS27064 (DoD Network Information Center); consistent with a single-homed .mil stub [Confirmed] — RIPEstat routing-status, bgp.he.net/AS384. No PeeringDB entry for AS384 specifically (org 20118 lists sibling ASNs in the block, not 384), so peering policy is not publicly published

[Confirmed for absence] — peeringdb.com/org/20118

RPKI

not assessable from this pass — RIPEstat rpki-validation was skipped (no --prefix supplied); bgp.he.net shows 0 RPKI-valid and 0 RPKI-invalid origins [Confirmed for bgp.he.net; Unknown for validated ROA state] — bgp.he.net/AS384

Notable usage

internal U.S. Air Force network infrastructure connected via DISA; interconnects with AS27064 (DoD NIC); no commercial or public-facing usage [Confirmed] — bgp.he.net/AS384, bgp.tools/as/384

Related ASNs

AS27064 (DoD Network Information Center, sole observed neighbour); sibling ASNs in the AFCONC-BLOCK1-AS block AS379–508 registered to the same Air Force Systems Networking org [Confirmed] — ARIN RDAP autnum/384, bgp.he.net/AS384

Analyst note

RDAP for "384" resolves to a range-level record (AS379–508, handle AS379); registrant/address/dates are inherited from that block and cross-corroborated, while prefix and upstream are AS384-specific. Website is Unknown — a government/military block has no operator corporate/about page. CAIDA AS-rank/cone data was unavailable (fetch timed out) and is left Unknown, not fabricated.
