AS132

AS132 is a legacy two-digit autonomous system registered under ARIN to Air Force Systems Networking (ARIN org handle 7ESG), a networking office of the United States Air Force. The AS name, WPAFB-CSD-NET-AS, points to Wright-Patterson Air Force Base in Ohio, where the office was originally headquartered; the current registrant address on file is the Gunther Annex at Maxwell AFB, Alabama, and the abuse and registration contacts are handled by DISA-Columbus (the Defense Information Systems Agency office in Whitehall, Ohio). The ARIN autnum carries a registration date of 1987-10-15, placing it among the early ASNs, with the autnum record last changed 2008-08-18. The most important triage point is that AS132 is dormant: it announces no IPv4 or IPv6 prefixes today, and RIPEstat sees it at none of its roughly 326 IPv4 and 320 IPv6 RIS peers. It was withdrawn from the global routing table around late February to early March 2024 (RIPEstat last observed 134.131.0.0/16 on 2024-02-14; Hurricane Electric reports it not visible since 2024-03-03). Historically it originated 134.131.0.0/16 plus two /24s in the 199.251.212–214 range, and its only recorded peer was AS367 (US DoD). CAIDA ranks it 79,459 with a customer cone of just itself and zero topology degree, and no RPKI records exist for its originated routes. No notable public abuse signal was found as of June 2026; it is a clean, currently-inactive U.S. military legacy ASN.
