AS470

AS470 is a U.S. Air Force autonomous system number registered under ARIN. It has no individual ARIN delegation record of its own — ARIN's registry groups it inside a single contiguous block registration, AFCONC-BLOCK1-AS, spanning AS379 through AS508, held by the ARIN organization "Air Force Systems Networking" (org handle 7ESG). Administrative, technical, and abuse contact for the block routes through DISA Columbus at Whitehall, Ohio, while the registrant address is the 754th Electronic Systems Group at Gunter Annex, Maxwell AFB, Alabama. Routing-wise, AS470 is long dormant: RIPEstat and CAIDA both show zero prefixes currently announced, zero visible RIS peers, and a CAIDA customer cone consisting only of the ASN itself. Historical routing data shows it was last seen in the global table around November 2012 (RIPEstat) or May 2012 (bgp.he.net) — sources disagree on the exact month but agree announcement ceased in 2012 — after having originated at least one /24 in the 131.16.240.0/24–131.16.242.0/24 range. No current public abuse or reputation signal was found; it is absent from Spamhaus ASN-DROP. An archived bgp.he.net note flags a historical (pre-2012, undated) "announces bogons" condition tied to that same reserved-space /24, a routing-hygiene artifact rather than a third-party abuse report. No PeeringDB entry or public peering policy exists, consistent with a closed DoD network.

Operator

Country / RIR

US, ARIN [Confirmed] — https://rdap.arin.net/registry/autnum/470

Allocated

1989-08-04 — RDAP autnum TOP-LEVEL registration event for the AFCONC-BLOCK1-AS block that covers AS470; corroborated independently by bgp.tools ("received its allocation from ARIN on August 4, 1989") [Confirmed] — https://rdap.arin.net/registry/autnum/470, https://bgp.tools/as/470

Org status

active (block registration status "active" in ARIN RDAP) [Confirmed] — https://rdap.arin.net/registry/autnum/470

Website

none found — no dedicated public site for ARIN org 7ESG or the administering 754th Electronic Systems Group; referenced only via other Air Force base domains' news pages [Unknown] — https://www.aflcmc.af.mil/WELCOME/Organizations/Electronic-Systems/

Security/abuse context (NEUTRAL, DATED)

no current public abuse signal found as of 2026-07-09; not present in Spamhaus ASN-DROP. Archived bgp.he.net note flags a historical, undated (pre-2012) "announces bogons" condition tied to originated prefix 131.16.240.0/24 — a routing-hygiene artifact, not a malicious-use report [Confirmed for absence from DROP; Likely for overall verdict] — https://www.spamhaus.org/drop/asndrop.txt, https://bgp.he.net/AS470

Network & routing

Network type

US Department of Defense / Air Force internal enterprise network, not a commercial ISP or transit provider [Confirmed] — https://whois.ipip.net/AS470

Routing status

not currently announced — 0 IPv4/IPv6 prefixes, 0 of 326 (v4) / 0 of 321 (v6) RIS peers seeing it; last seen in the global table 2011/2012 (RIPEstat: first_seen 2011-11-11, last_seen 2012-11-14 for prefix 131.16.240.0/24–131.16.242.0/24; bgp.he.net independently states "not visible since May 1, 2012" — minor date discrepancy between sources, both agree on 2012 cessation)

[Confirmed] — https://stat.ripe.net/AS470, https://bgp.he.net/AS470

CAIDA

AS rank 79459; customer cone = 1 ASN (itself), 0 prefixes, 0 addresses; AS degree total/customer/peer/provider all 0; seen=false, clique=false [Confirmed] — https://asrank.caida.org/asns/470

RPKI

not evaluable — no prefixes currently announced, so no ROAs to validate against; RIPEstat rpki-validation requires a prefix argument [Unknown] — https://stat.ripe.net/data/rpki-validation/data.json

Peering policy / PeeringDB

no public entry or policy found, consistent with a closed government/military network [Unknown] — https://www.peeringdb.com/asn/470

Block registration

AS470 falls inside ARIN's contiguous block AFCONC-BLOCK1-AS (AS379–AS508); ARIN returns handle "AS379" for any ASN in that range, including AS470 — this is why the RDAP record's handle differs from the queried number [Confirmed] — https://rdap.arin.net/registry/autnum/470

Last changed

2008-06-06 (RDAP autnum top-level "last changed" event) [Confirmed] — https://rdap.arin.net/registry/autnum/470

Historical peer

AS27139 (US Department of Defense Network Information Center), per bgp.he.net's last-observed (pre-2012) peer data; no current peers observed by any live source [Likely] — https://bgp.he.net/AS470

Analyst note

AS470 is a dormant DoD/Air Force block-registration ASN with no individual ARIN delegation, unrouted since 2012, no notable abuse signal, and no public peering presence.
