AS717

AS717 is an ARIN-registered autonomous system held by the United States Department of Defense (DoD) that is currently unannounced — it originates zero IPv4 and zero IPv6 prefixes anywhere in the global routing table today.

The registrant is the DoD (ARIN handle USDDD, address 3990 E. Broad Street, Columbus, OH 43218), with network operations pointed at DISA-Columbus. The ASN's RDAP registry name is DNIC-AS-00717, reflecting its origin in ARIN's legacy DNIC (Defense Network Information Center) allocation block. The RDAP autnum object's top-level events carry only a "last changed" timestamp (2025-09-12); no top-level "registration" event exists, so the original allocation date is genuinely unrecoverable from the authoritative record — this was confirmed with a full untruncated re-fetch, not a parsing artifact.

Routing telemetry is unanimous across sources: RIPEstat shows 0 announced v4/v6 prefixes and 0 of ~328/324 RIS peers observing it; CAIDA AS Rank places it at 79,459 with total degree 0 (no customers, peers, or providers) and a customer cone limited to itself; bgp.he.net and bgp.tools independently confirm zero announced prefixes and zero visible BGP peers. No PeeringDB record exists for AS717, and RPKI validation does not apply since nothing is announced to validate.

Beyond the registry facts, little is confirmed publicly. No first-party DoD page (disa.mil, defense.gov) could be retrieved to confirm which internal network, if any, this ASN maps to, so that mapping stays unasserted rather than guessed.

Operator

United States Department of Defense (DoD); network operations via DISA-Columbus [Confirmed] — ARIN RDAP autnum 717

Country / RIR

US, ARIN [Confirmed] — ARIN RDAP autnum 717

Allocated

Unknown — RDAP autnum top-level events[] contains only a "last changed" entry (2025-09-12), no "registration" event; re-verified with an untruncated fetch, so this is a genuine registry gap, not a fetch error [Confirmed absence] — rdap.arin.net/registry/autnum/717

Org status

active per ARIN RDAP; registrant United States Department of Defense, handle USDDD [Confirmed] — ARIN RDAP autnum 717

Contacts

disa.columbus.ns.mbx.hostmaster-dod-nic@mail.mil; +1-844-347-2457 ext2; registrant address 3990 E. Broad Street, Columbus, OH 43218 [Confirmed] — ARIN RDAP autnum 717

Security/abuse context (NEUTRAL, DATED)

no notable public abuse signal found as of 2026-07-25 — not in Spamhaus ASN-DROP or NANOG archives; a stale/unrelated ALTDB IRR entry ("DediRoom LLC") is noise, not a real conflict

Network & routing

Network type

Likely a non-commercial, DoD-internal government/military network (legacy DNIC-block allocation, registry name DNIC-AS-00717); no first-party source confirms a specific mapping (e.g. NIPRNet) [Likely] — ARIN RDAP autnum 717

Size

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

Routing/peering

NOT announced — 0/328 RIS peers see it (v4), 0/324 (v6); CAIDA degree total 0 (customer 0, peer 0, provider 0); no PeeringDB record [Confirmed]

RPKI

not assessable — no announced prefixes exist to validate against ROAs [Confirmed] — stat.ripe.net/AS717

Notable usage

no confirmed current operational use; allocated-but-unannounced DoD ASN. Official DoD web properties (disa.mil, defense.gov) did not yield accessible confirmation of a specific use [Unknown] — disa.mil, defense.gov (both inaccessible during research)

Related ASNs

none identified with confidence in this research pass [Unknown]

Analyst note

Registry-confirmed DoD ASN that is currently unannounced across all routing sources checked; the allocation date is a genuine RDAP gap (only a "last changed" event exists), not a fabricated or nulled-on-suspicion value. Official operator website could not be verified (disa.mil returned an unrelated placeholder, defense.gov/About/ returned HTTP 403).
