Autonomous system detail

AS465

Not announced

Operated by AFCONC-BLOCK1-AS - Air Force Systems Networking.

Summary

// analyst note
Autnum record handle is AS379 (block AS379-508, name AFCONC-BLOCK1-AS) — normal ARIN pattern for large government block registrations, named after the block's first ASN. AS465 last routed pre-2018 with two Thailand-based National Telecom peers (AS9931, AS4651), a single-source historical detail (bgp.he.net) flagged rather than treated as settled fact.
// security note
NEUTRAL/DATED: no notable public abuse signal found as of 2026-07-09 across bgp.he.net, IPinfo, Spamhaus resource pages, and NANOG/seclists archives.

About this ASN.

Updated  ·  Confidence: High

AS465 is a legacy autonomous system number that falls inside a large contiguous ARIN block, handle AS379, spanning AS379 through AS508 and registered under the name AFCONC-BLOCK1-AS. The registrant organization (ARIN org handle 7ESG) is "Air Force Systems Networking," with the ASN's day-to-day registration administration handled by DISA Columbus (contact handle REGIS10-ARIN) rather than the Air Force directly. ARIN's RDAP record shows this autnum was registered on 1989-08-04, a first-party RIR fact carried at the record's top level, and last modified on 2008-06-06. Every routing-data source consulted — RIPEstat routing-status, CAIDA AS Rank, and bgp.he.net — agrees AS465 currently announces zero IPv4 and zero IPv6 prefixes and has zero visible BGP neighbors, upstreams, or customers, giving it a CAIDA rank of 79,459 and a singleton customer cone. bgp.he.net further indicates the ASN dropped out of the global routing table around 2018-02-01, with its last observed IPv4 peers being two Thailand-based National Telecom entities (AS9931, AS4651) — a single-source historical detail worth flagging rather than treating as settled fact. No public abuse signal, dedicated operator website, or published peering policy exists for AS465; PeeringDB's entry for the same organization (org/20118) lists five other ASNs but not AS465 itself.

Operator / registrant
Air Force Systems Networking (ARIN org handle 7ESG); ASN-registration administration delegated to DISA Columbus (POC handle REGIS10-ARIN, disa.columbus.ns.mbx.arin-registrations@mail.mil) [Confirmed] — https://rdap.arin.net/registry/autnum/465
Country / RIR
US, ARIN [Confirmed] — https://rdap.arin.net/registry/autnum/465
Allocated
1989-08-04 — ARIN RDAP autnum top-level "registration" event (first-party RIR fact, confirmed independently by three angles); last changed 2008-06-06 (top-level "last changed" event) [Confirmed] — https://rdap.arin.net/registry/autnum/465
Org status
ARIN registry status is "active" for the containing autnum record; operationally the ASN is inactive/unrouted since ~2018 — a routing-activity observation, not a registry-status fact, and the two should not be conflated [Confirmed] — https://rdap.arin.net/registry/autnum/465
Website
no dedicated public operator website found for AS465 or AFCONC-BLOCK1-AS; af.mil is only a generic Air Force portal, not AS465-specific [Likely] — https://ipinfo.io/AS465

Security/abuse context (NEUTRAL, DATED)

no notable public abuse signal found as of 2026-07-09 across bgp.he.net, IPinfo, Spamhaus resource pages, and NANOG/seclists archives; AbuseIPDB and Shodan InternetDB were deliberately excluded per repo licensing policy

[Confirmed] — https://bgp.he.net/AS465, https://www.spamhaus.org/blocklists/do-not-route-or-peer/

Network & routing

Network type
non-commercial, closed U.S. DoD/Air Force network; not a commercial ISP despite third-party aggregator IPinfo's generic "ISP, Business or Hosting" bucket tag [Likely] — https://ipinfo.io/AS465
Size / routing state
0 IPv4 prefixes / 0 IPv4 addresses, 0 IPv6 prefixes; customer cone = singleton (1 ASN, 0 prefixes, 0 addresses) [Confirmed] — https://stat.ripe.net/AS465, https://asrank.caida.org/asns/465
Routing/peering
NOT announced — 0 of 326 RIS peers see it in IPv4, 0 of 321 in IPv6; CAIDA degree total 0 (customer 0, peer 0, provider 0); observed_neighbours 0 [Confirmed] — https://stat.ripe.net/AS465#tabId=routing, https://asrank.caida.org/asns/465
Historical routing
dropped from the global table around 2018-02-01; last observed IPv4 peers were AS9931 and AS4651 (both National Telecom Public Company Limited, Thailand), with no abuse association found [Likely, single-source] — https://bgp.he.net/AS465
Peering policy
no operator-published peering policy exists for AS465; PeeringDB org/20118 ("Air Force Systems Networking") lists AS65, AS123, AS175, AS221, AS301 but not AS465, and that record has no populated peering-policy field [Likely] — https://www.peeringdb.com/org/20118
RPKI
not assessable — AS465 announces no prefixes, so no ROAs exist to validate [Confirmed] — https://stat.ripe.net/AS465
Notable usage
none observed publicly — dormant/unrouted allocation with no hosted domains, no active peers/upstreams/downstreams [Confirmed] — https://ipinfo.io/AS465
Geo footprint
registrant address 501 East Moore Dr, Bldg 884 Rm 1100, Gunter Annex, Maxwell AFB, AL 36114; admin/abuse POC address 300 North James Road, Whitehall, OH 43213 (DISA-Columbus); CAIDA holds no real geocoordinates (0,0 placeholder, seen:false)
[Confirmed] — https://rdap.arin.net/registry/autnum/465, https://asrank.caida.org/asns/465
Related ASNs
block-mate ASNs AS379–AS508 share the AFCONC-BLOCK1-AS record; PeeringDB org/20118 (same "Air Force Systems Networking" organization) separately lists AS65, AS123, AS175, AS221, AS301 [Confirmed for block range; Likely for the PeeringDB list's relatedness] — https://rdap.arin.net/registry/autnum/465, https://www.peeringdb.com/org/20118
ASN / block record
AS465, held within ARIN autnum record handle AS379 (block range AS379–AS508), name AFCONC-BLOCK1-AS [Confirmed] — https://rdap.arin.net/registry/autnum/465
Assignment class
allocated, legacy government/military block (large contiguous DoD/Air Force ASN range, not an ISP allocation) [Confirmed] — https://rdap.arin.net/registry/autnum/465
Analyst note
the autnum record's handle is "AS379," not "AS465" — ARIN names large government block registrations after the block's first ASN, so AS465 correctly resolves through this AS379–AS508 record; this is a normal ARIN pattern, not a data error [Confirmed] — https://rdap.arin.net/registry/autnum/465
