AS587

AS587 is a U.S. Department of Defense autonomous system number allocated by ARIN on 1990-02-07 to Air Force Systems Networking, an organizational registrant based at Maxwell AFB, Alabama. The registry name GDSS-ANG-AS hints at a Global Decision Support System / Air National Guard tie, but no independent source confirms that expansion, so it is treated as an unverified label rather than a fact. Day-to-day administrative, abuse, and technical contact duties sit with DISA-Columbus, which manages the ARIN registration on the Air Force's behalf from Whitehall, Ohio. Despite an "active" RDAP status, AS587 is currently dormant on the public Internet: every routing source checked — RIPEstat, CAIDA AS Rank, and bgp.tools — independently agrees it originates zero IPv4 and zero IPv6 prefixes, has zero visible peers, zero upstreams, and a customer cone limited to itself. CAIDA ranks it 79,459th globally, near the bottom of the table, with no clique membership and an unlocated (0,0) coordinate consistent with a network that isn't announcing routes for a BGP-derived geolocation to attach to. No PeeringDB record exists for AS587 specifically, and no public peering policy could be found. No notable abuse signal turned up in Spamhaus, Talos, or NANOG archive searches as of this check; a 2025 "Salt Typhoon" campaign against Army National Guard networks surfaced in research but is explicitly a different branch/system and was ruled out rather than attributed here.

Operator / registrant

Air Force Systems Networking (ARIN org handle 7ESG), 501 East Moore Dr., Bldg 884 Rm 1100, Gunther Annex, Maxwell AFB, AL 36114, US [Confirmed] — https://rdap.arin.net/registry/entity/7ESG

Country / RIR

US, ARIN [Confirmed] — https://rdap.arin.net/registry/autnum/587

Allocated

1990-02-07 (ARIN RDAP autnum TOP-LEVEL "registration" event); last changed 2009-05-08 (top-level "last changed" event) — entity-level dates on REGIS10-ARIN and 7ESG (2009/2008) are org/POC record dates and were excluded [Confirmed] — https://rdap.arin.net/registry/autnum/587

RIR status

active (ARIN RDAP autnum status) [Confirmed] — https://rdap.arin.net/registry/autnum/587

Website

Unknown — no dedicated public operator website could be confirmed; a possible institutional pointer (aflcmc.af.mil) returned HTTP 403 and its content could not be verified [Unknown]

Security/abuse context (NEUTRAL, DATED)

no notable public abuse signal found as of 2026-07-11 in Spamhaus ASN-DROP, Cisco Talos, or NANOG archives; a 2025 Salt Typhoon campaign against Army National Guard networks is a distinct branch/system and was checked and ruled out, not attributed to AS587

Network & routing

Network type

government/military (U.S. Air Force administrative network), not a commercial ISP [Likely] — https://rdap.arin.net/registry/autnum/587, https://bgp.tools/as/587

Routing/size

NOT currently announced — 0 IPv4 and 0 IPv6 prefixes; 0/325 v4 and 0/322 v6 RIS peers seeing it; 0 observed neighbours; customer cone limited to itself (1 ASN, 0 prefixes, 0 addresses)

[Confirmed] — https://stat.ripe.net/AS587, https://api.asrank.caida.org/v2/restful/asns/587, https://bgp.tools/as/587

AS rank

CAIDA AS Rank 79459; cliqueMember false; seen false; lat/long 0,0 (unlocated, consistent with an unrouted ASN) [Confirmed] — https://api.asrank.caida.org/v2/restful/asns/587

Peering

no PeeringDB net record found for AS587 specifically (org 20118 lists sibling ASNs AS65/AS123/AS175/AS221/AS301/AS570/AS581-586, not AS587); no public peering policy documented [Unknown] — https://www.peeringdb.com/org/20118

RPKI

not assessable — AS587 announces no prefixes, so there are no ROAs to validate; RIPEstat rpki-validation was skipped (requires a prefix parameter) [Unknown] — https://stat.ripe.net/AS587

Notable usage

RDAP network name "GDSS-ANG-AS" may point to a Global Decision Support System / Air National Guard association, but this expansion is unconfirmed by any independent second source [Unknown] — https://rdap.arin.net/registry/autnum/587

Admin/abuse/technical contact

Analyst note

dormant/legacy-in-practice DoD ASN — RDAP status is "active" and the allocation date is a confirmed first-party ARIN fact, but the ASN currently originates nothing and is invisible in the global routing table.
