AS295

AS295 is a legacy autonomous system number registered under ARIN to the United States Department of Defense, administered through the Defense Information Systems Agency (DISA) and its DoD Network Information Center (DoD NIC) under org handle USDDD. The ARIN registry AS name is USTCCLOUD, which points to a U.S. Transportation Command (USTRANSCOM) cloud-networking context — USTRANSCOM was the first DoD component to migrate to commercial cloud (a 2017 award to REAN Cloud LLC), though no first-party record ties AS295 to a specific program with certainty. The key triage point is that AS295 is dormant today: every routing source consulted (RIPEstat, CAIDA AS Rank, IPinfo, CIDR Report) agrees it announces zero IPv4 and zero IPv6 prefixes, has zero visible BGP peers, zero upstreams, zero customers, and no IXP memberships. Its CAIDA AS rank of 79,459 sits near the bottom of the global ranking, and its customer cone is a singleton (the ASN itself, 0 prefixes, 0 addresses). The ASN was historically active — RIPEstat records first-seen routing on 2000-08-18 (138.145.0.0/16) and last-seen on 2021-10-28 (140.16.40.0/21) — but it is withdrawn from BGP at query time. RPKI posture cannot be assessed because there are no active originations and therefore no ROAs. No notable public abuse signal was found as of June 2026 — not in Spamhaus ASN-DROP, AbuseIPDB, NANOG archives, or BGP-incident records — consistent with a clean, dormant ASN held by a federal/military operator; the DoD NIC ISP umbrella carries a 0/100 Scamalytics fraud score.

Security/abuse context (NEUTRAL, DATED)

no notable public abuse signal found as of 2026-06-26 — not in Spamhaus ASN-DROP (checked against the ~Jan 2026 dataset), AbuseIPDB, NANOG abuse threads, or BGP-incident records; DoD NIC ISP umbrella scores 0/100 on Scamalytics; dormant ASN with no active attack surface

Network & routing

Network type

U.S. federal government / military — DoD internal network infrastructure; AS295 is legacy/inactive [Confirmed for operator; Likely for the USTRANSCOM cloud association inferred from the AS name] — ARIN RDAP, ipinfo.io/AS295

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 node 295 (2026-06)

Routing/peering

NOT announced — 0 RIS peers seeing it (0/325 v4, 0/323 v6); CAIDA degree total 0 (customer 0, peer 0, provider 0); no upstreams or peers visible in any source [Confirmed]. Historically routed: first seen 2000-08-18, last seen 2021-10-28 [Confirmed] — RIPEstat routing-status. No AS295-specific PeeringDB entry; sibling DoD NIC ASNs show 'Open' policy

[Likely] — peeringdb.com

RPKI

not assessable — AS295 announces no prefixes, so there are no ROAs to validate; RIPEstat rpki-validation requires an active prefix [Unknown] — RIPEstat

Notable usage

ARIN AS name USTCCLOUD suggests allocation in a U.S. Transportation Command (USTRANSCOM) cloud context; USTRANSCOM was the first DoD component to migrate to commercial cloud (2017, REAN Cloud LLC). AS295 currently announces no routes

Related ASNs

DoD NIC (USDDD) administers ~95 ASNs; siblings on PeeringDB include AS749, AS244, AS360, AS650, AS769, AS27081 [Confirmed for the USDDD org block; Likely for the specific sibling list per third-party DB] — rdap.arin.net/registry/entity/USDDD, peeringdb.com

Analyst note

Encountered as a dormant legacy ASN registered to the U.S. DoD via DISA/DoD NIC. WHOIS resolves to DoD; historically routed until 2021, now withdrawn from BGP. Clean, inactive ASN.
