AS716

AS716 is a dormant U.S. Army autonomous system — registered to Headquarters, USAISC (United States Army Information Systems Command) and administered on ARIN via DISA-Columbus — that currently announces zero IPv4 and zero IPv6 prefixes across every routing source checked.

The ASN's ARIN registry name is DNIC-AS-00716, marking it as a legacy Defense Network Information Center block. The registrant address is a Theater Network Operations and Security Center at Fort Huachuca, AZ; the administrative/abuse contact is DISA-Columbus. As a military ASN, it has no public operator website, no about page, and no PeeringDB net record (a direct query for AS716 returned HTTP 404).

Routing sources agree unanimously on dormancy: RIPEstat shows 0 of 328 RIS peers see it on IPv4 and 0 of 324 on IPv6; CAIDA AS Rank places it at 79,459 with a customer cone of just the ASN itself (0 prefixes, 0 addresses) and zero customer/peer/provider degree; bgp.he.net independently shows 0 originated prefixes and 0 observed peers; ipinfo.io classifies the ASN "Inactive." No peering policy is published, and RPKI cannot be assessed because there are no announced prefixes to validate.

The allocation date is recorded as Unknown by design, not by omission: the autnum's own top-level RDAP events array carries only a "last changed" event (2011-08-02), with no "registration" eventAction — confirmed not a truncation artifact by re-fetching the raw JSON directly. Two nearby dates exist in the same record but belong to different objects and were deliberately not used as the allocation date: the registrant org entity (HEADQU-3) has its own registration event dated 1990-03-26, and the technical/abuse contact entity (REGIS10-ARIN) has one dated 2009-06-24. Neither is the autnum's own registration event.

Operator

Headquarters, USAISC (United States Army Information Systems Command) — ARIN org handle HEADQU-3, registry name DNIC-AS-00716; administered via DISA-Columbus [Confirmed] — ARIN RDAP autnum/716

Country / RIR

US, ARIN [Confirmed] — ARIN RDAP autnum/716

Allocated

Unknown — autnum top-level RDAP events[] contains only a "last changed" event (2011-08-02T10:55:28-04:00), no "registration" eventAction; verified not truncated via a direct raw-JSON re-fetch. Entity-level dates exist but are NOT the ASN's allocation date: org HEADQU-3 registered 1990-03-26; technical contact REGIS10-ARIN registered 2009-06-24

[Confirmed] — ARIN RDAP autnum/716

Org status

active (ARIN RDAP autnum status) [Confirmed] — ARIN RDAP autnum/716

Contacts

disa.columbus.ns.mbx.arin-registrations@mail.mil (DISA-Columbus registration/abuse contact, REGIS10-ARIN); registrant address Fort Huachuca, AZ 85613; admin/technical address 300 North James Road, Whitehall, OH 43213 [Confirmed] — ARIN RDAP autnum/716, RIPEstat abuse-contact-finder

Security/abuse context (NEUTRAL, DATED)

not on Spamhaus ASN-DROP as of 2026-07-25; ipinfo.io classifies the ASN "Inactive"; bgp.he.net corroborates 0 originated prefixes / 0 peers; no NANOG-archive abuse mentions found (limited search, not exhaustive)

Network & routing

Network type

Government/military ASN (U.S. Army Information Systems Command via DISA-Columbus); legacy DNIC (Defense Network Information Center) block; not a commercial ISP [Likely] — bgp.he.net/AS716, ARIN RDAP

Size

dormant — 0 IPv4 / 0 IPv6 announced prefixes; customer cone = 1 ASN (itself), 0 prefixes, 0 addresses [Confirmed] — RIPEstat routing-status, CAIDA AS Rank, bgp.he.net (2026-07-25)

Routing/peering

NOT announced — 0/328 RIS peers see it (IPv4), 0/324 (IPv6); CAIDA degree total 0 (customer 0, peer 0, provider 0); no PeeringDB net record (404) and no published peering policy [Confirmed] — RIPEstat, CAIDA AS Rank, peeringdb.com/api/net?asn=716

RPKI

not assessable — AS716 announces no prefixes, so RIPEstat's prefix-scoped rpki-validation could not be run; no ROAs to validate [Unknown] — RIPEstat

Notable usage

Unknown beyond its registration purpose; registrant address "NETC-ANC CONUS TNOSC, Fort Huachuca, AZ" (Theater Network Operations and Security Center) is consistent with U.S. Army network operations; no independent operator-authored usage page found [Likely] — ARIN RDAP autnum/716

Related ASNs

none identified this cycle (isolated military DNIC allocation; no sibling ASNs surfaced by any angle) [Unknown]

Analyst note

Legacy DNIC military ASN held by U.S. Army Headquarters USAISC, currently dark in the public DFZ — RIPEstat, CAIDA, bgp.he.net, and ipinfo.io all independently agree on zero announcements. Allocation date deliberately left null rather than borrowed from a nearby entity-level RDAP date. Community corroboration (A5) abstained this cycle on search-budget exhaustion.
