AS414

AS414 is a legacy autonomous system number registered under ARIN to Air Force Systems Networking, the networking arm of the United States Air Force within the Department of Defense. It falls inside the AFCONC-BLOCK1-AS block, a contiguous range of ASNs (AS379 through AS508) that ARIN administers as a single block-level RDAP object rather than carving out a separate per-ASN record for AS414 itself. The registrant organization (ARIN handle 7ESG) lists an address at 501 East Moore Dr., Bldg 884, Rm 1100, Gunther Annex, Maxwell AFB, Alabama, and the abuse/registration contact routes to DISA-Columbus at Whitehall, Ohio (disa.columbus.ns.mbx.arin-registrations@mail.mil). The defining triage point for AS414 is that it is currently dark: every routing source consulted agrees it announces zero IPv4 and zero IPv6 prefixes. RIPEstat reports announced=false with 0 of 323 IPv4 RIS peers and 0 of 321 IPv6 RIS peers observing it, and 0 observed neighbours. CAIDA AS Rank places it at #79,459 with a customer cone of just itself (0 prefixes, 0 addresses) and an AS degree of zero across customers, peers, and providers. RPKI posture is not assessable because there are no announced prefixes to validate. No notable public abuse signal was found as of 2026-07-02 — not in Spamhaus SBL/DROP, abuse.ch, or NANOG archives — consistent with a clean, dormant government-allocated ASN. Community sources associate the broader Air Force Systems Networking function with the 754th Electronic Systems Group at Hanscom AFB, though that organizational attribution is single-sourced and not RDAP-confirmed. The 1989-08-04 allocation date is the block's top-level ARIN registration event and is recorded here as AS414's allocated_date.

Operator

Air Force Systems Networking (U.S. Air Force / Department of Defense; ARIN org handle 7ESG, part of AFCONC-BLOCK1-AS) [Confirmed] — ARIN RDAP autnum/414, bgp.he.net/AS414

Country / RIR

US, ARIN [Confirmed] — RIPEstat abuse-contact-finder (authoritative_rir: arin), ipinfo.io/AS414

Allocated

1989-08-04 (ARIN registry top-level registration event for the AFCONC-BLOCK1-AS block covering AS379–AS508; NOT an IEEE date); last changed 2008-06-06 [Confirmed] — ARIN RDAP autnum top-level events. Note: ARIN returns a block-level autnum object (handle AS379, startAutnum 379, endAutnum 508) for the AS414 query; the nested entity events (7ESG 2008-06-05, REGIS10-ARIN 2009-06-24) are org/POC record dates, not the allocation date, and were excluded.

Org status

registered but flagged Inactive by ipinfo.io (last update on file 2008-06-06); consistent with zero current routing activity [Confirmed] — ipinfo.io/AS414

Contacts

disa.columbus.ns.mbx.arin-registrations@mail.mil (DISA-Columbus, Whitehall, OH); registrant address Maxwell AFB, AL 36114 [Confirmed] — ARIN RDAP autnum/414, RIPEstat abuse-contact-finder

Security/abuse context (NEUTRAL, DATED)

no notable public abuse signal found as of 2026-07-02 — not in Spamhaus SBL/DROP, abuse.ch, or NANOG archives (WebSearch reconnaissance, not an exhaustive authenticated query). Unrelated 2023 Air Force communications-compromise news and the Teixeira Discord leak were NOT attributed to AS414 — no ASN-level sourcing ties them to this ASN or block

Network & routing

Network type

U.S. military / government internal ASN block; AS414 is legacy/dormant (currently announces nothing) [Confirmed] — bgp.he.net/AS414, RIPEstat as-overview

Size

dormant — 0 IPv4 prefixes / 0 IPv4 addresses and 0 IPv6 prefixes; customer cone = 1 ASN (itself), 0 prefixes, 0 addresses [Confirmed] — RIPEstat routing-status / CAIDA AS Rank

Routing/peering

NOT announced — RIPEstat announced=false; 0 RIS peers seeing it (0/323 v4, 0/321 v6); CAIDA degree total 0 (customer 0, peer 0, provider 0); no upstreams or peers visible [Confirmed] — RIPEstat, CAIDA. No PeeringDB net record exists for ASN 414 (queried live, no result)

[Confirmed] — peeringdb.com/api/net?asn=414

RPKI

not assessable — AS414 announces no prefixes, so there are no ROAs to validate; RIPEstat rpki-validation skipped (requires a prefix) [Unknown] — RIPEstat

Notable usage

none publicly documented specific to AS414; the ASN is dormant/not routing. Community sources tie Air Force Systems Networking broadly to the 754th Electronic Systems Group, Hanscom AFB [Likely] — hanscom.af.mil article 381978 (single-sourced, org-level, not RDAP-confirmed for AS414)

Related ASNs

AS379–AS508 (the AFCONC-BLOCK1-AS sibling block registered to the same org) [Confirmed] — ARIN RDAP autnum/414

Analyst note

Encountered as a dormant legacy ASN in a DoD-registered block. ARIN serves it via a block-level RDAP record (AS379–AS508); dates are the block's top-level events. Clean, inactive ASN with no public web/peering presence (verified via WebSearch + PeeringDB, reported as sourced Unknown rather than left blank).
