AS769

AS769 (DNIC-AS-00769) is a dormant autonomous system registered to the United States Department of Defense that announces zero IPv4 and zero IPv6 prefixes on the public Internet today. ARIN RDAP records the DoD (entity handle USDDD) as registrant, with the ASN administratively handled through the DoD Network Information Center (DoD NIC), a function of DISA's Columbus, Ohio field office.

Every routing source consulted agrees AS769 is unannounced: RIPEstat shows 0 of 328 RIS peers seeing an IPv4 route and 0 of 322 seeing an IPv6 route, with zero observed BGP neighbours. CAIDA's AS Rank places it at #79,459, not a clique member and not seen in topology, with a customer cone limited to itself — 0 prefixes, 0 addresses — and zero customer, peer, or provider relationships in its degree count.

ARIN's RDAP autnum record for AS769 carries a top-level registration event dated 1990-10-31, making it a long-standing DoD allocation, with the record last changed 2025-09-12. No live, current official DoD NIC website exists to corroborate further detail — the historical nic.mil domain is defunct, preserved only in a 2008 Internet Archive capture, and DISA's own web properties returned only generic portal placeholder content rather than ASN-specific documentation when checked.

PeeringDB lists AS769 with a general policy of "Open" (no contract required, no ratio requirement) but a route-server policy of "Never via route servers," and no IRR as-set, looking glass, or exchange-point presence — a self-submitted directory listing rather than an operator-authored peering policy document. RPKI posture cannot be assessed because the ASN announces no prefixes and there are no ROAs to validate.

Security/abuse context (NEUTRAL, DATED)

no notable public abuse signal found as of 2026-08-01 — not in Spamhaus ASN-DROP (txt+json checked live), NANOG archives, or general web search; unrelated to the 1997 AS 7007 incident [Confirmed for Spamhaus check; Likely for absence of other signal] — spamhaus.org/drop/asndrop.json

Network & routing

Network type

not disclosed on any operator-official page found; PeeringDB shows no protocols marked supported and 0 IPv4/IPv6 prefixes announced, consistent with a closed government network rather than a commercial ASN, but no operator statement defines it [Unknown/Likely] — peeringdb.com/asn/769

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 (2026-07/08)

Routing/peering

NOT announced — 0/328 v4 and 0/322 v6 RIS peers see it; CAIDA asnDegree total 0 (customer 0, peer 0, provider 0); PeeringDB lists a general policy of "Open" (contract not required, no ratio requirement) but a route-server policy of "Never via route servers"; no IRR as-set, looking glass, or IX presence [Confirmed for non-announcement; Likely for PeeringDB policy fields, self-submitted] — stat.ripe.net/AS769, api.asrank.caida.org, peeringdb.com/asn/769

RPKI

not assessable — AS769 announces no prefixes, so there are no ROAs to validate [Confirmed] — stat.ripe.net/AS769

Notable usage

Unknown — no operator-published description of AS769's specific traffic was found; DoD NIC (which registers AS769) also administers the .mil TLD generally, but that role is not documented as tied to this specific ASN [Unknown] — rdap.arin.net/registry/autnum/769, iana.org/domains/root/db/mil.html

Related ASNs

Unknown — no AS769-specific related-ASN list was found; it is one of many "DNIC-AS-xxxxx" block ASNs registered directly to the DoD and administered via DoD NIC, not individually enumerated in sourced data [Unknown]

Analyst note

Encountered as a dormant, long-standing (registered 1990) DoD-registered ASN with no live routing and thin public documentation — consistent with a closed government network rather than an abandoned commercial allocation. Live-routing status could not be attributed to any sibling ASN because no related-ASN list was sourced.
