AS799

AS799 is a dormant Department of Defense ASN, registered under ARIN as DNIC-AS-00799 to Headquarters, USAISC (U.S. Army Information Systems Command), that currently announces zero IPv4 and zero IPv6 prefixes anywhere in the global routing table.

ARIN's RDAP record shows the autnum's top-level registration event dated 1990-12-18, with a last-changed event of 2011-08-02. The registrant address is Fort Huachuca, Arizona, and the administrative/technical contact is the DoD Network Information Center, routed through DISA-Columbus in Whitehall, Ohio. Third-party corroboration suggests the parent USAISC organization was administratively inactivated on 1996-10-01, with functions folded into Army Signal Command — but AS799 itself remains an active, independent ARIN registration unaffected by that internal reorganization.

Routing data from RIPEstat and CAIDA AS Rank agree the ASN is completely unrouted: 0 of 328 RIS peers see it over IPv4 and 0 of 322 over IPv6, CAIDA reports zero customer/peer/provider degree, and the customer cone is a singleton — itself only, 0 prefixes, 0 addresses. CAIDA ranks it 79,459 globally. No PeeringDB network record exists for ASN 799 (API returns 404), consistent with a DoD administrative allocation that does not publish a commercial-style peering policy.

An attempt to reach the likely present-day operating command's public site, Army NETCOM (netcom.army.mil, headquartered at the same Fort Huachuca location as the ARIN registrant), returned HTTP 403 on every fetch, so operator-site corroboration beyond the RDAP record itself is Unknown rather than confirmed. This unrouted pattern is typical of reserved/administrative military ASNs whose traffic, if any, moves over non-public defense infrastructure invisible to public route collectors.

Operator

Headquarters, USAISC (U.S. Army Information Systems Command); DoD Network Information Center (DNIC) is the administrative/technical contact [Confirmed] — ARIN RDAP autnum 799

Country / RIR

US, ARIN [Confirmed] — ARIN RDAP autnum 799

Allocated

1990-12-18 (ARIN RDAP autnum top-level registration event); last changed 2011-08-02 [Confirmed] — ARIN RDAP autnum top-level events (entity-level dates on REGIS10-ARIN and HEADQU-3 are decoys and were not used)

Org status

active independent ARIN registration [Confirmed]; the broader parent organization "Headquarters, USAISC" is reported by third-party sources as administratively inactivated 1996-10-01 with functions transferred to Army Signal Command [Likely] — acronymfinder.com, ARIN RDAP

Contacts

DoD Network Information Center (handle REGIS10-ARIN), DISA-Columbus, 300 North James Road, Whitehall, OH 43213; disa.columbus.ns.mbx.arin-registrations@mail.mil; +1-844-347-2457 ext2; registrant address NETC-ANC CONUS TNOSC, Fort Huachuca, AZ 85613 [Confirmed] — ARIN RDAP

Security/abuse context (NEUTRAL, DATED)

no notable public abuse signal found as of 2026-08-01 — not in Spamhaus ASN-DROP (checked live), NANOG mailing-list archives, or AbuseIPDB/threat-actor coverage; consistent with a dormant, unrouted DoD allocation

Network & routing

Network type

U.S. military/DoD network (DNIC-prefixed ASN); currently administrative/dormant, not actively routed [Confirmed] — ARIN RDAP; RIPEstat routing-status

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/announced-prefixes; CAIDA AS Rank (2026-08)

Routing/peering

NOT announced — 0 RIS peers seeing it (0/328 v4, 0/322 v6); CAIDA degree total 0 (customer 0, peer 0, provider 0); no PeeringDB net record (404) [Confirmed]

RPKI

not assessable — AS799 announces no prefixes, so there are no ROAs to validate [Confirmed] — RIPEstat

Notable usage

DoD/U.S. Army network infrastructure ASN administered via the DoD Network Information Center (DNIC) allocation block; not currently routed [Confirmed] — ARIN RDAP

Related ASNs

none confidently identified in this research pass (DNIC block context noted, but no specific sibling ASN was verified first-party) [Unknown]

Analyst note

Dormant DoD/Army ASN, unrouted across all four routing sources consulted (RIPEstat, CAIDA, RIS, PeeringDB). WHOIS/RDAP resolves to Headquarters, USAISC via the DNIC allocation block; the likely present-day operating command (Army NETCOM) could not be first-party-verified as its site returned HTTP 403 on every fetch attempt.
