About this ASN.

Updated  ·  Confidence: High  ·  3 sources  ·  How this page is checked

AS65 is a legacy allocation registered under ARIN to Air Force Systems Networking (org 7ESG, Gunter Annex, Maxwell AFB, AL), a U.S. Air Force networking organization — the same USAF lineage that holds the sibling AS61. RFC 1020 (1987) lists AS65 as "LOGNET-AS" (some legacy mirrors label it "754th Electronic Systems Group"); the current ARIN holder is Air Force Systems Networking. Unlike several dormant military DNIC numbers, AS65 is actively announcing: as of June 2026 about two IPv4 prefixes (129.19.163.0/24 and 192.111.86.0/24) and no IPv6 (512 addresses), with upstream/peer the University Corporation for Atmospheric Research (UCAR, AS14041); 129.19.163.0/24 is RPKI-valid while the other is unauthenticated. The registration/abuse contact routes through DISA Columbus, consistent with DoD network administration. The ARIN ASN RegDate is 1986-03-18 (the 7ESG org RegDate is 2008-06-05). The 7ESG org holds a large pool of legacy ASNs (AS61, AS132, AS136, the AS379–508 block, AS416, AS491, AS494). For triage this is an actively-routed U.S. Air Force network. No notable public abuse signal was found as of June 2026.
