AS485

AS485 (AFCONC-BLOCK1-AS) is an actively routed autonomous system registered to Air Force Systems Networking, a U.S. Department of the Air Force network-engineering program. As observed by RouteViews at 2026-08-14 19:00 PDT (2026-08-15 02:00 UTC), it originates five IPv4 prefixes totaling 2,304 addresses and zero IPv6 prefixes — a small, currently-live network, not a dormant registration.

The RouteViews RIB dump recorded exactly one AS_PATH-adjacent ASN, AS27064 — the complete observed set, not a capped sample. Adjacency data carries no relationship-direction signal, so whether AS27064 acts as a transit provider, a customer, or a settlement-free peer of AS485 cannot be determined from this source; no source in this entry establishes an upstream for AS485.

Air Force Systems Networking (AFSN) is a live federal program name — the title of a Department of the Air Force network-engineering contract vehicle listed on SAM.gov — rather than an independent commercial entity. AFSN performs design, installation, and sustainment of Air Force classified and unclassified wired and wireless networks, including portions of the Joint Regional Security Stack (JRSS) and Joint Information Environment (JIE), for Active Duty, Reserve, Guard, and DoD sites.

Country and RIR of record (US, ARIN) follow from the AS name's registry-style prefix and are reported as Likely rather than independently confirmed. Allocation and last-registry-update dates are Unknown. A third-party federal-contract tracker reports AFSN program activity continuing into mid-2025, consistent with AS485's current live routing.

Exposure surface

Minimal observed footprint — RouteViews recorded five originated IPv4 prefixes and exactly one AS_PATH-adjacent ASN (AS27064) as of 2026-08-15; relationship direction is not available, so upstream, customer, or peer posture cannot be characterized.

Public visibility

No public peering-policy document was found (August 2026 search), and no NANOG mailing-list discussion of AS485 was found as of 2026-08-15 — consistent with DoD-internal infrastructure rather than a reliability or transparency concern, though neither search was exhaustive.

Operator

Air Force Systems Networking (AFSN), a U.S. Department of the Air Force network-engineering program — confirmed as a live federal contract-vehicle name via a SAM.gov opportunity listing, not an independent commercial entity. A tie to the Business and Enterprise Systems Directorate (Air Force Life Cycle Management Center, Gunter Annex, Montgomery AL) rests on a subcontractor's description rather than a directly-verified Air Force primary source [Likely] — https://sam.gov/opp/8eecf7a4a668447487ec1f23ee9e62ba/view, https://solutions71.com/air-force-systems-networking-afsn/, https://www.aflcmc.af.mil/WELCOME/Organizations/Business-and-Enterprise-Systems-Directorate/

Org status

Likely active — no direct registry-status source is available, but AS485 is currently originating routes (RouteViews, 2026-08-14 19:00 PDT / 2026-08-15 02:00 UTC) and a third-party federal-contract tracker reports AFSN program activity continuing into mid-2025

Contacts

Unknown as of 2026-08-15 — no contact information for AS485 or Air Force Systems Networking was found [Unknown]

Security/abuse context (NEUTRAL, DATED)

no notable public abuse signal found as of 2026-08-15 — not listed in Spamhaus ASN-DROP; no subnet within its announced 144.88.0.0/16 space appears on the SANS ISC top-attacking-networks list; CleanTalk's tracker shows 0.00% spam activity on the one AS485 prefix it monitors, 144.88.224.0/22

Network & routing

Network type

government/military — Air Force Systems Networking is a U.S. Department of the Air Force network-engineering program, not a commercial ISP [Confirmed] — https://solutions71.com/air-force-systems-networking-afsn/

Size

5 IPv4 prefixes / 2,304 addresses; 0 IPv6 prefixes, as observed by RouteViews at 2026-08-14 19:00 PDT (2026-08-15 02:00 UTC) [Confirmed] — the RouteViews BGP routing data (CC BY 4.0) AS485

Routing/peering

as observed by RouteViews at 2026-08-14 19:00 PDT (2026-08-15 02:00 UTC), exactly one AS_PATH-adjacent ASN was recorded, AS27064 — the complete observed neighbor set, not a capped sample; relationship direction (upstream, customer, or peer) is not available from this data. CAIDA-style rank, customer-cone size, and IX presence are Unknown as of 2026-08-15 [Confirmed adjacency; Unknown relationship/rank/cone/IX] — the RouteViews BGP routing data (CC BY 4.0) AS485

Peering policy

not publicly located as of an August 2026 search — no peering-policy document or page was found for Air Force Systems Networking, AFCONC-BLOCK1-AS, or AS485 specifically; consistent with DoD-internal infrastructure but not a certainty that none exists anywhere [Unknown]

RPKI

Unknown as of 2026-08-15 — no RPKI route-origin validation status is currently available for AS485's five announced prefixes [Unknown]

Notable usage

part of the Air Force Enterprise Network (AFNET) numbering pool; the AFSN program performs design, installation, and sustainment of Air Force classified/unclassified wired and wireless networks, including portions of the Joint Regional Security Stack (JRSS) and Joint Information Environment (JIE), across Active Duty, Reserve, Guard, and DoD sites CONUS and OCONUS

Related ASNs

AS27064 observed as the sole AS_PATH-adjacent ASN in RouteViews data; relationship direction is unknown, so it is reported here as an observed neighbor, not a confirmed upstream or sibling [Confirmed adjacency; Unknown relationship] — the RouteViews BGP routing data (CC BY 4.0) AS485. Other Air Force-operated ASNs may share the same holder-name pattern, but none is independently confirmed as of 2026-08-15 [Unknown]

Analyst note

AS485 is a small, currently-live U.S. Air Force/DoD network — 5 IPv4 prefixes (2,304 addresses, no IPv6) and exactly one AS_PATH-adjacent ASN (AS27064) as observed by RouteViews on 2026-08-15. Relationship direction to AS27064, RPKI coverage, CAIDA rank, customer-cone size, IX presence, and registry allocation/last-updated dates are all Unknown. No public abuse signal was found across three independent trackers as of 2026-08-15.
