AS455

AS455 is a legacy autonomous system number registered under ARIN to "Air Force Systems Networking," a United States Air Force / Department of Defense network resource administered on the registration side by DISA (Defense Information Systems Agency), Columbus, OH, with the registrant organization object listed as Maxwell AFB–Gunter Annex, Alabama. The ARIN RDAP record covering AS455 is not a per-ASN record but a contiguous block object spanning AS379 through AS508 (handle "AS379," name "AFCONC-BLOCK1-AS"); this block-level registration carries a top-level registration event dated 1989-08-04 and a last-changed event dated 2008-06-06. AS455 today shows no live routing footprint: RIPEstat reports it as not announced, with zero IPv4 and zero IPv6 prefixes visible to any of the 325 v4 / 321 v6 RIS route-collector peers, and CAIDA's AS Rank places it at rank 79,459 with a customer cone limited to itself (1 ASN, 0 prefixes, 0 addresses) and all degree counts (customer/peer/provider) at zero. bgp.he.net's last observed routing-table state (before the ASN went fully dark) shows AS455 has not been visible in the global routing table since November 1, 2022, and that its final recorded BGP entry was a single IPv4 prefix, 1.22.125.0/24 — flagged by bgp.he.net as a bogon route, since that space is legitimately allocated to Tikona Infinet Ltd., an Indian ISP (AS45528), not to a US Air Force network. That mismatch is a routing-table anomaly worth flagging but is not a confirmed, named hijack incident; no NANOG postmortem or threat-intel listing (Spamhaus, AbuseIPDB, Project Honey Pot) names AS455 specifically. No PeeringDB network object, public peering policy, or operator website exists for AS455, consistent with an internally administered military ASN block that is not marketed or peered commercially.

Operator

Air Force Systems Networking (AFCONC-BLOCK1-AS), a US Air Force/DoD network resource; registrant org handle 7ESG, address 501 East Moore Dr., Maxwell AFB, AL 36114 [Confirmed] — ARIN RDAP (https://rdap.arin.net/registry/autnum/455)

Country / RIR

US, ARIN [Confirmed] — RIPEstat abuse-contact-finder (authoritative_rir: arin)

Allocated

1989-08-04 (ARIN RDAP autnum TOP-LEVEL registration event for the AS379–AS508 block object that contains AS455); last changed 2008-06-06 [Confirmed] — ARIN RDAP autnum top-level events (https://rdap.arin.net/registry/autnum/455)

Org status

active (ARIN status: active) as a registry object; operationally the ASN itself shows no live routing activity [Confirmed] — ARIN RDAP

Security/abuse context (NEUTRAL, DATED)

no notable public abuse signal found as of 2026-07-05 across Spamhaus, AbuseIPDB, Project Honey Pot, or NANOG/seclists archives; AS455 has been inactive/withdrawn from the global routing table since 2022-11-01, which limits current abuse exposure

Network & routing

Network type

government/military network (US Air Force); not a commercial ISP, hosting provider, or enterprise network [Likely] — ipinfo.io/AS455, en.ipshu.com/asn/455

Size / routing status

not announced — 0 IPv4 and 0 IPv6 prefixes visible to RIS peers (0/325 v4, 0/321 v6); CAIDA customer cone = 1 ASN (itself), 0 prefixes, 0 addresses; not visible in the global BGP table since 2022-11-01 [Confirmed] — RIPEstat routing-status/announced-prefixes, CAIDA AS Rank, bgp.he.net/AS455

Routing/peering

no upstreams, peers, or IXP presence observed (CAIDA asnDegree customer/peer/provider all 0; RIPEstat observed_neighbours 0); no PeeringDB network object found for AS455 [Confirmed] — RIPEstat, asrank.caida.org/asns/455, peeringdb.com

RPKI

not evaluated — RIPEstat rpki-validation requires a specific prefix parameter and AS455 announces none [Unknown] — stat.ripe.net

Notable usage

no ASN-specific notable public usage documented; broader AFCONC-BLOCK1-AS range was flagged in 2012 RIPE routing-wg BGP Update Reports among unstable/high-churn origin ASes in specific periods, but that commentary does not name AS455 specifically [Unknown] — ripe.net routing-wg archive

Important caveat

the ARIN RDAP record is a block-level object (handle AS379, startAutnum 379, endAutnum 508) covering many contiguous ASNs (e.g. AS379, AS416, AS486, AS455), not a record scoped uniquely to AS455 — the allocated/last-changed dates are the block's top-level registration dates, reported per RIR-first-party-fact convention, not an AS455-unique allocation transaction

[Confirmed] — ARIN RDAP

Historical/last-seen anomaly

last recorded BGP entry (pre-inactivity) originated 1.22.125.0/24, flagged as a bogon by bgp.he.net since that block belongs to Tikona Infinet Ltd. (AS45528, India), not to AS455; sole observed historical peer was AS45528 — a routing-table anomaly, not a confirmed named hijack

[Likely] — bgp.he.net/AS455

Analyst note

block-level ARIN record shared across a contiguous DoD/Air Force ASN range; AS455 itself is long-dormant with a single documented historical bogon-flagged route as its last BGP footprint.
