AS586

AS586 is a legacy autonomous system number registered under ARIN to Air Force Systems Networking, a U.S. Air Force / Department of Defense network administered by DISA-Columbus. The ARIN RDAP record's top-level autnum registration event places the ASN's allocation at 1990-02-07, with the record last changed 2009-05-08; the registrant's technical/administrative/abuse point of contact is DISA-Columbus (Whitehall, OH), while the registrant organization's postal address is Gunter Annex, Maxwell AFB, Alabama — both are DoD facilities, not a commercial ISP presence. Every routing source consulted (RIPEstat, CAIDA AS Rank, bgp.he.net, bgp.tools) agrees AS586 currently announces zero IPv4 and zero IPv6 prefixes, has zero visible BGP peers, zero upstreams, and zero downstream customers; RIPEstat's RIS visibility shows 0 of 325 v4 peers and 0 of 322 v6 peers seeing it. CAIDA's AS Rank places it at 79,459, near the bottom of the global ranking, with a customer cone that is a singleton (itself, 0 prefixes, 0 addresses) — consistent with an allocated-but-dormant, non-routed federal ASN. No PeeringDB network record exists for AS586 itself (the "Air Force Systems Networking" PeeringDB org lists other ASNs — 65, 123, 175, 221, 301 — but not 586). The AS name "GDSS-834ALD-AS" superficially resembles the real USAF/USTRANSCOM Global Decision Support System program, but no source directly ties this ASN to that system, so that connection is left unconfirmed rather than recorded as fact. No notable public abuse signal was found as of 2026-07-11 — AS586 does not appear in the Spamhaus ASN-DROP list and no NANOG or threat-intelligence writeups name it — consistent with a dormant, unrouted legacy DoD ASN with essentially no abuse surface.

AS name

GDSS-834ALD-AS [Confirmed] — https://rdap.arin.net/registry/autnum/586

Country / RIR

US, ARIN [Confirmed] — https://rdap.arin.net/registry/autnum/586

Allocated

1990-02-07 (ARIN RDAP top-level autnum registration event — first-party RIR fact, recorded per policy, not an IEEE/third-party artifact); last changed 2009-05-08 [Confirmed] — https://rdap.arin.net/registry/autnum/586

Org status

active per ARIN RDAP (status: active), but CAIDA shows an essentially isolated, unrouted customer cone [Confirmed] — https://rdap.arin.net/registry/autnum/586, https://asrank.caida.org/asns/586

Contacts

disa.columbus.ns.mbx.arin-registrations@mail.mil; org address 501 East Moore Dr., Bldg 884, Rm 1100, Gunter Annex, Maxwell AFB, AL 36114 [Confirmed] — https://rdap.arin.net/registry/autnum/586

Security/abuse context (NEUTRAL, DATED)

no notable public abuse signal found as of 2026-07-11 — not present in Spamhaus ASN-DROP; no NANOG or threat-feed incident reports naming AS586; consistent with a dormant, non-routed legacy federal ASN

Network & routing

Network type

U.S. government/military (DoD) network, not a commercial ISP [Likely] — https://rdap.arin.net/registry/autnum/586

Size

dormant — 0 announced IPv4 and 0 IPv6 prefixes, 0 address estimate; customer cone = 1 ASN (itself), 0 prefixes, 0 addresses [Confirmed] — https://bgp.he.net/AS586, https://asrank.caida.org/asns/586

Routing/peering

NOT announced — 0 RIS peers seeing it (0/325 v4, 0/322 v6); CAIDA degree total 0 (customer 0, peer 0, provider 0); no PeeringDB network record for AS586 itself [Confirmed] — https://bgp.he.net/AS586, https://www.peeringdb.com/org/20118

RPKI

not assessable — AS586 announces no prefixes, so there are no ROAs to validate (RIPEstat rpki-validation skipped for lack of a prefix) [Confirmed] — https://stat.ripe.net/586

Notable usage

Unconfirmed/speculative only — the AS name resembles the USAF "Global Decision Support System" (GDSS) program, but no source ties AS586 itself to it; not recorded as fact [Unknown] — https://www.ustranscom.mil/foia/docs/pia/Archive/gdss2_pia.pdf

Analyst note

Allocated-but-unrouted legacy DoD ASN; registrant is Air Force Systems Networking, admin contact is DISA-Columbus. No fabricated link drawn between the AS name and the real GDSS program.
