Announced

Operated by DNIC-AS-00056 - United States Department of Defense (DoD).

Summary

// analyst note
Large, live DoD production network (925 IPv4 prefixes, ~8M addresses, last-seen 2026-06-19). An AS56 origin in BGP is expected and legitimate DoD routing — do NOT treat it as suspect.
// security note
NEUTRAL/DATED: no notable public abuse signal found as of 2026-06-19.

About this ASN.

Updated  ·  Confidence: High

AS56 is a legacy U.S. government allocation registered under ARIN to the United States Department of Defense (org USDDD), administered through the DoD Network Information Center in Columbus, OH. Potaroo's legacy-autnums mirror records the original 1980s label as "OPTIMIS-P — OPTIMIS Division," indicating the number was first tied to the DoD "OPTIMIS" management-information effort before being consolidated under the modern USDDD org record. The ARIN ASN RegDate is 1985-12-18, marking it as one of the earliest defense AS allocations; tech, NOC and abuse contacts all route through the DoD NIC (DISA Columbus). Far from dormant, AS56 is a large, actively routed DoD network: at the 2026-06-19 capture RIPEstat saw 925 IPv4 prefixes originated (~7,979,008 addresses, roughly a /9-equivalent of mostly legacy class-B and class-C DoD space such as 131.x, 132.x, 137.x and 143.x ranges), with very high global visibility (326 of 327 RIS full-feed peers) and last-seen today (131.35.0.0/16). No IPv6 is originated. Reported upstream/transit is DISA (AS27064 / AS27065); three observed BGP neighbours overall. For triage this is a genuine, live DoD production network — an AS56 origin in BGP is expected and legitimate, not suspect. It belongs to the same DoD/DNIC allocation family as its sibling DoD numbers (e.g., AS2054) and the Army HEADQU-3 pool. No notable public abuse signal was found as of June 2026.
