AS83

AS83 is a legacy DoD/DNIC allocation registered under ARIN to Headquarters, USAISC (the U.S. Army Information Systems Command, Fort Huachuca, AZ), in the HEADQU-3 org family, carrying the handle "DNIC-AS-00083." RFC 1020 (1987) labeled it "PICANET-AS," tied to the U.S. Army Armament Research, Development and Engineering Center at Picatinny Arsenal, NJ — so this is a clear case of a legacy number whose label and holder both changed. The ASN is dormant: it shows zero IPv4, zero IPv6, and zero prefixes (Confirmed via db-ip/ARIN), and is not present in the global routing table as of June 2026. The ARIN RDAP RegDate is 1986-08-07. For triage this is a classic registered-but-dormant Army DNIC-AS number; if it ever appears in live traffic or AS paths, treat as anomalous/spoofed and investigate. No notable public abuse signal was found as of June 2026.
