AS314

AS314 is a legacy autonomous system number registered under ARIN to the United States Department of Defense (DoD), administered through the DoD Network Information Center (DNIC) and operated via the Defense Information Systems Agency (DISA). It is not a standalone allocation: ARIN registers it as one slot inside the block object DNIC-ASBLK-00306-00371, a single RDAP autnum spanning AS306 through AS371 (66 ASNs) that the registry allocated to the DoD on 1989-06-30. The key triage point for AS314 is that it is dormant. Every routing source consulted agrees it announces zero IPv4 and zero IPv6 prefixes, is not present in the global routing table (announced=false per RIPEstat, queried 2026-06-27), and shows zero RIS peers and zero observed neighbours. The only routing history RIPEstat retains is a narrow window of brief BGP visibility between 2001-09-26 (199.33.16.0/24) and 2003-01-21 (130.38.0.0/16), after which the ASN went quiet. RPKI posture is not assessable because there are no active originations and therefore no ROAs to validate, and CAIDA AS Rank was unavailable (HTTP 502) so no rank or customer-cone figure could be obtained. No public abuse signal was found as of 2026-06-28 — AS314 is not in the Spamhaus ASN-DROP list (timestamped 2026-06-25), and no NANOG threads or threat-feed hits surfaced. Registry contacts route to DISA's Columbus, Ohio facility. This is a clean, inactive government/military ASN held in a reserved legacy DoD block.

Network & routing

Network type

government / military; AS314 is a legacy/dormant slot in a DoD ASN block (AS306–AS371) [Confirmed] — ARIN RDAP autnum/314, bgp.he.net/AS314, bgp.tools/as/314

Size

dormant — 0 IPv4 prefixes / 0 IPv4 addresses and 0 IPv6 prefixes [Confirmed] — RIPEstat routing-status (announced=false), https://stat.ripe.net/data/routing-status/data.json?resource=314

Routing/peering

NOT announced — announced=false; 0 RIS peers seeing it (0/323 v4, 0/321 v6); 0 observed neighbours; no upstreams or peers visible in any source [Confirmed] — RIPEstat as-overview / routing-status (2026-06-27)

Routing history

brief BGP visibility from 2001-09-26 (first seen, 199.33.16.0/24) to 2003-01-21 (last seen, 130.38.0.0/16); none since [Confirmed] — RIPEstat routing-status, https://stat.ripe.net/data/routing-status/data.json?resource=314

RPKI

not assessable — AS314 announces no prefixes, so there are no ROAs to validate; RPKI validation skipped (no prefix) [Unknown] — RIPEstat rpki-validation (skipped, no --prefix)

AS rank / customer cone

Unknown — CAIDA AS Rank API returned HTTP 502; not obtainable this run [Unknown] — api.asrank.caida.org (502)

Peering policy

Unknown — no PeeringDB entry for AS314 (404); DoD publishes no open peering policy for its reserved block members [Confirmed for absence] — https://www.peeringdb.com/asn/314

Notable usage

AS314 is a reserved/unactivated slot in the DoD's DNIC-ASBLK-00306-00371 block (AS306–AS371), managed by DISA's Columbus facility; currently advertising no prefixes [Confirmed] — ARIN RDAP autnum/314, bgp.he.net/AS314

Analyst note

Encountered as a dormant legacy ASN inside a DoD block object; WHOIS resolves to the U.S. DoD via DISA Columbus, but the ASN carries no live routing. Clean, inactive ASN. Community angle abstained (no public NANOG/Reddit/forum footprint) — honest null, not refutation.
