AS410

AS410 is a legacy autonomous system number registered under ARIN to Air Force Systems Networking, the registrant organization identity for a block of U.S. Air Force / Department of Defense network space administered by DISA Columbus. It is not a discrete standalone ARIN object: ARIN returns a block/range representation (handle AFCONC-BLOCK1-AS, startAutnum 379, endAutnum 508) that AS410 falls inside, and RIPEstat's independent as-overview query for resource 410 confirms the holder as "AFCONC-BLOCK1-AS - Air Force Systems Networking." The key triage point is that AS410 is dormant. Every routing source consulted agrees it announces zero IPv4 and zero IPv6 prefixes and carries no visible BGP relationships: RIPEstat routing-status shows 0 of 323 RIS peers seeing any v4 route and 0 of 321 seeing v6, and CAIDA AS Rank reports total degree 0 (0 customer, 0 peer, 0 provider), a singleton customer cone (1 ASN, 0 prefixes, 0 addresses), not seen in topology, no clique membership, no IXP presence, and rank 79,459. RPKI posture cannot be assessed because there are no announced prefixes and therefore no ROAs. No notable public abuse signal was found as of 2026-07-02 — not in Spamhaus SBL/XBL/DROP/ASN-DROP, AbuseIPDB, or NANOG mailing-list archives — consistent with a clean, unrouted government ASN with no traffic to generate abuse reports. The registrant address of record is Maxwell AFB, Alabama, with DISA Columbus (Whitehall, OH) as the abuse/administrative/technical contact.

Operator

Air Force Systems Networking (ARIN registrant org, handle 7ESG; U.S. Air Force / DoD network space administered by DISA Columbus) — not a separate corporate legal entity but the ARIN-registered organization identity for this block [Confirmed] — ARIN RDAP autnum/410, ipinfo.io/AS410

Country / RIR

US, ARIN [Confirmed] — RIPEstat abuse-contact-finder (authoritative_rir: arin); CAIDA country.iso US

Allocated

1989-08-04 (ARIN registry top-level autnum registration event for the AFCONC-BLOCK1-AS block containing AS410, NOT an IEEE date — IEEE publishes no ASN registration dates); last changed 2008-06-06 [Confirmed] — ARIN RDAP autnum/410 top-level events

Org status

ARIN registration active/valid (not revoked); operationally inactive (no announced routes/prefixes) [Confirmed] — ipinfo.io/AS410

Contacts

Security/abuse context (NEUTRAL, DATED)

no notable public abuse signal found as of 2026-07-02 — not in Spamhaus SBL/XBL/DROP/ASN-DROP, AbuseIPDB, or NANOG mailing-list archives; dormant/unrouted government ASN with no traffic to generate reports

Network & routing

Network type

U.S. government / military network (Air Force / DoD information network space); IPinfo's generic taxonomy label reads "ISP, Business or Hosting" but the registrant identity and Maxwell AFB address confirm DoD/USAF infrastructure, not a commercial ISP; AS410 is legacy/inactive

[Confirmed] — ipinfo.io/AS410

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 (2026-07)

Routing/peering

NOT announced — 0 RIS peers seeing it (0/323 v4, 0/321 v6); CAIDA degree total 0 (customer 0, peer 0, provider 0); RIPEstat observed_neighbours 0; no upstreams or peers visible in any source [Confirmed]. No AS410-specific peering policy is published; a PeeringDB org named "Air Force Systems Networking" (org 20118) exists but its listed ASNs do NOT include AS410, so its policy is not attributable here

[Unknown] — RIPEstat routing-status, CAIDA AS Rank, peeringdb.com/org/20118

RPKI

not assessable — AS410 announces no prefixes, so there are no ROAs to validate; RIPEstat rpki-validation was skipped (requires a prefix) [Confirmed] — RIPEstat

Notable usage

none currently — AS410 is unannounced and absent from the global routing table. It sits within a large Air Force-allocated ASN block (AS379–AS508), most of whose individual numbers are likewise unannounced [Confirmed] — ipinfo.io/AS410, RIPEstat

Analyst note

RDAP returns a block object (handle AS379 / AFCONC-BLOCK1-AS, range 379–508) rather than a single-ASN object for AS410; the top-level events (registration 1989-08-04, last changed 2008-06-06) are the authoritative allocation/update dates for the block, corroborated as covering AS410 by RIPEstat's independent as-overview. Entity-nested dates (registrant 7ESG reg 2008-06-05; contact REGIS10-ARIN reg 2009-06-24) are decoys and were not used for allocated_date.
