AS583

AS583 (GDSS-22AF-AS) is a legacy autonomous system number registered under ARIN to Air Force Systems Networking (org handle 7ESG), a U.S. Air Force / Department of Defense network engineering organization headquartered at 501 East Moore Drive, Bldg 884 Rm 1100, Gunther Annex, Maxwell AFB, Alabama. ARIN's RDAP record for the autnum object shows a top-level registration event dated 1990-02-07, with the record last changed 2009-05-08. The AS name GDSS ties this ASN to the Global Decision Support System, an Air Mobility Command command-and-control platform, consistent with web corroboration linking AS583 to AMC's mobility-operations infrastructure. Unlike a commercial network, AS583 functions as a purely internal DoD asset: it has no entry in PeeringDB, no public peering policy, and no dedicated public-facing website. Every routing data source consulted — RIPEstat, CAIDA ASRank, and bgp.he.net — agrees the ASN is currently not announced: zero originated IPv4 and IPv6 prefixes, zero observed BGP neighbours, and zero visibility across all 325 IPv4 and 322 IPv6 RIS route-collector peers. CAIDA ranks it 79,459th globally with a customer cone limited to itself (1 ASN, 0 prefixes, 0 addresses). No public abuse, hijack, or blocklist activity was found for AS583, consistent with a dormant, non-routed government ASN rather than an actively operated commercial network.

Allocated

1990-02-07 (ARIN RDAP autnum top-level registration event — first-party RIR fact, distinct from the nested REGIS10-ARIN contact-entity date of 2009-06-24 and the 7ESG org-entity date of 2008-06-05, which are decoys); last changed 2009-05-08 [Confirmed] — https://rdap.arin.net/registry/autnum/583

Org status

active in ARIN registry; org handle 7ESG registered 2008-06-05, last updated 2025-03-13; AS583 record itself shows status "active" with no terminated/reclaimed marker [Confirmed] — https://rdap.arin.net/registry/autnum/583, https://whois.arin.net/rest/org/7ESG.html

Contacts

abuse/admin/tech via REGIS10-ARIN — DISA-Columbus, 300 North James Road, Whitehall, OH 43213, US; email disa.columbus.ns.mbx.arin-registrations@mail.mil; tel +1-844-347-2457 ext2 (status: validated) [Confirmed] — https://rdap.arin.net/registry/autnum/583

Security/abuse context (NEUTRAL, DATED)

no notable public abuse, hijack, spam, or botnet signal found as of 2026-07-11 across Spamhaus, a public ASN-blacklist compilation, and NANOG archive search; consistent with a non-publicly-routed DoD ASN rather than a commercially operated one

Network & routing

Network type

government/military network — U.S. Air Force / DoD, associated with GDSS (Global Decision Support System), an Air Mobility Command C2 platform; not a commercial ISP, transit, or content network [Confirmed] — https://rdap.arin.net/registry/autnum/583, https://www.amc.af.mil/News/Article-Display/Article/148923/amc-unveils-new-generation-command-and-control-system/

Size

dormant — 0 IPv4 prefixes / 0 addresses and 0 IPv6 prefixes; customer cone = 1 ASN (itself), 0 prefixes, 0 addresses [Confirmed] — RIPEstat routing-status / announced-prefixes (resource=583), CAIDA ASRank API (fetched 2026-07-11)

Routing/peering

NOT announced — 0/325 v4 and 0/322 v6 RIS peers see it, observed_neighbours=0; CAIDA degree total 0 (customer 0, peer 0, provider 0); no PeeringDB record (peeringdb.com/asn/583 returns HTTP 404, verified live) [Confirmed] — RIPEstat routing-status, CAIDA ASRank API, https://www.peeringdb.com/asn/583

RPKI

not assessable — AS583 announces no prefixes, so there are no relevant ROAs; RIPEstat's rpki-validation endpoint was skipped for lack of a prefix parameter [Confirmed] — RIPEstat rpki-validation (resource=583)

Notable usage

per a Wright-Patterson AFB public-affairs article, Air Force Systems Networking (AFSN) provides design analysis, testing, implementation, installation, and project management for network engineering supporting Active Duty Air Force, Air Force Reserve Command, Air National Guard, and other DoD sites.

Related ASNs

none confirmed — this record is adjacent in the GDSS naming series (GDSS-22AF-AS) but no specific related-ASN list was corroborated by two sources [Unknown]

Analyst note

legacy, dormant DoD ASN. WHOIS/RDAP resolves to Air Force Systems Networking (7ESG) at Maxwell AFB, but the AS-name (GDSS-22AF-AS) and web corroboration tie it to the Global Decision Support System, an Air Mobility Command C2 system. No public routing presence in any source checked.
