About this ASN.

Updated  ·  Confidence: High

AS123 is a legacy summer-1987 allocation registered under ARIN to Air Force Systems Networking (ARIN OrgID 7ESG), carrying the handle "LOGAIRCOMNET-AS" — a legacy U.S. Air Force logistics-network allocation whose historical RFC-era expansion was Air Force Logistics Command-related (LOGAIRCOMNET = Logistics Air Force Communications Network). The same OrgID 7ESG ("754th Electronic Systems Group" / Air Force Systems Networking) holds several other early Air Force ASNs, including AS107 (profiled earlier in this sweep), AS132, AS133, and AS136. The ARIN autnum RegDate is 1987-08-24 (registry updated 2008-08-18; org RegDate 2008-06-05). It is confirmed dormant — bgp.tools states it is an inactive BGP network, it originates 0 IPv4 / 0 IPv6 prefixes, and it is not in the global routing table. For triage this is encountered only in registry/historical research, not live traffic. No abuse signal is possible since it is not announcing routes (as of June 2026).
