AS416

AS416 is a legacy autonomous system number registered under ARIN as part of AFCONC-BLOCK1-AS, a bulk ASN range block spanning AS379–AS508 held by Air Force Systems Networking (AFSN), a U.S. Air Force / Department of Defense networking program administered by the Defense Information Systems Agency (DISA). Rather than being individually delegated, AS416 sits inside this range-registered ARIN autnum object (handle AS379, startAutnum 379, endAutnum 508) — a registration pattern typical of the early, pre-CIDR bulk ASN grants made to military and government organizations. The registrant of record is org handle 7ESG, "Air Force Systems Networking," at 501 East Moore Dr., Bldg 884, Rm 1100, Gunter Annex, Maxwell AFB, AL 36114; administrative, technical, and abuse handling routes to DISA-Columbus (REGIS10-ARIN) at 300 North James Road, Whitehall, OH, via disa.columbus.ns.mbx.arin-registrations@mail.mil. The key triage point for AS416 is that it is effectively dormant today. Every routing source consulted (RIPEstat, CAIDA AS Rank, bgp.he.net, IPinfo) agrees it announces zero IPv4 and zero IPv6 prefixes, has zero visible BGP peers, zero upstreams, and zero customers. RIPEstat shows no RIS peer visibility (0/324 v4, 0/320 v6), and its only historical routing footprint is a brief window in 2019 (prefix 219.70.0.0/17 first seen 2019-06-24; 61.71.0.0/16 last seen 2019-08-07). CAIDA ranks it 79,459 with a singleton customer cone and an AS degree of zero across the board, and IPinfo marks the ASN status Inactive. RPKI posture is not assessable — with no announced prefixes there are no ROAs to validate. No notable public abuse signal was found as of July 2026 (not in Spamhaus ASN-DROP, NANOG archives, or general threat-intel), consistent with a clean, dormant government ASN. Community records note only a historical BGP-instability report from May 2012 for the parent AFCONC block; no post-2012 incidents surfaced.

Operator

Air Force Systems Networking (U.S. Air Force / DoD; administered by DISA), ARIN org handle 7ESG, part of AFCONC-BLOCK1-AS [Confirmed] — ARIN RDAP (https://rdap.arin.net/registry/autnum/416)

Country / RIR

US, ARIN [Confirmed] — RIPEstat abuse-contact-finder (authoritative_rir: arin) (https://stat.ripe.net/data/abuse-contact-finder/data.json?resource=416)

Allocated

1989-08-04 (ARIN registry date for the AFCONC-BLOCK1-AS range that contains AS416, a first-party RIR fact — NOT an IEEE date; IEEE publishes no ASN registration dates); last changed 2008-06-06 [Confirmed] — ARIN RDAP autnum top-level events (https://rdap.arin.net/registry/autnum/416)

Org status

active per ARIN RDAP (status: active) — a legitimate, currently-registered U.S. government ASN block, not reclaimed/reserved-unused, though it shows no independent public operator presence beyond the RIR record [Confirmed] — ARIN RDAP (https://rdap.arin.net/registry/autnum/416)

Website

Unknown — no dedicated operator website, PeeringDB network page, or .mil page specific to AS416 or the AFCONC-BLOCK1-AS block found (general DISA site disa.mil, general USAF af.mil) [Unknown] — peeringdb.com/org/20118, disa.mil

Security/abuse context (NEUTRAL, DATED)

no notable public abuse signal found as of 2026-07-02 — not in Spamhaus ASN-DROP, NANOG archives, or general threat-intel; USAF-wide security news was NOT attributable to AS416 specifically; a historical bgp.he.net peer artifact (AS9416, unrelated Taiwanese org) is noted but uncorroborated and not treated as a finding

Network & routing

Network type

U.S. federal government / military network under the Air Force Systems Networking program and the broader DoD Information Network (DODIN); not a commercial ISP, hosting, or transit provider [Likely] — DoDI 8010.01 (https://www.esd.whs.mil/Portals/54/Documents/DD/issuances/dodi/801001p.pdf)

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 / bgp.he.net (2026-07)

Routing/peering

NOT announced — 0 RIS peers seeing it (0/324 v4, 0/320 v6); CAIDA degree total 0 (customer 0, peer 0, provider 0); no upstreams or peers visible; only historical BGP presence was a 2019 window (219.70.0.0/17 first seen 2019-06-24; 61.71.0.0/16 last seen 2019-08-07); IPinfo marks status Inactive [Confirmed] — RIPEstat routing-status (https://stat.ripe.net/data/routing-status/data.json?resource=416), bgp.he.net/AS416, ipinfo.io/AS416

Peering policy

none active / not publicly published for AS416; no PeeringDB network record exists for this ASN (PeeringDB org 20118 lists other Air Force ASNs, not AS416) [Confirmed for absence] — peeringdb.com/org/20118

RPKI

not assessable — AS416 announces no prefixes, so there are no ROAs to validate; RIPEstat rpki-validation was skipped (requires a --prefix) [Unknown/N-A] — RIPEstat rpki-validation (skipped, no --prefix)

Notable usage

none found tying distinct traffic to AS416; the parent AFCONC-BLOCK1-AS range is associated with legacy pre-CIDR DoD ASN allocations (block registration 1989) rather than modern per-network delegation [Likely] — ARIN RDAP (https://rdap.arin.net/registry/autnum/416)

Geo footprint

CAIDA country US (lat/long 0, no precise geocoding); RDAP registrant address Maxwell AFB, AL 36114; RDAP admin/abuse/tech (DISA-Columbus) Whitehall, OH 43213 [Confirmed] — ARIN RDAP, CAIDA AS Rank (https://api.asrank.caida.org/v2/restful/asns/416)

Block registration

range-registered autnum AS379–AS508, name AFCONC-BLOCK1-AS, handle AS379 (startAutnum 379, endAutnum 508); AS416 is not a standalone record but falls within the block [Confirmed] — ARIN RDAP (https://rdap.arin.net/registry/autnum/416)

Community context

AFCONC-BLOCK1-AS appears in a May 2012 NANOG-reported BGP-instability period; no post-2012 community incidents found; limited public visibility is consistent with a military network posture [Confirmed for 2012 report; Likely for follow-up absence] — lists.archive.carbon60.com/nanog/users/153051

Analyst note

Encountered as a dormant legacy range-registered ASN under a U.S. Air Force / DISA-administered block; WHOIS/RDAP resolves to Air Force Systems Networking, but the ASN carries no current routing and is marked Inactive. Entity-level dates (REGIS10-ARIN registration 2009-06-24; org 7ESG registration 2008-06-05) are decoys — the allocated_date is strictly the autnum top-level registration event (1989-08-04). Clean, inactive government ASN.
