AS68

AS68 is a legacy allocation registered under ARIN to Los Alamos National Laboratory (org LANL-2-Z, Los Alamos, NM), a U.S. Department of Energy / NNSA national laboratory operated by Triad National Security, LLC, focused on nuclear-weapons stockpile stewardship and multidisciplinary science. The canonical ARIN ASName is "LANL-NM" (comment "Main Campus"); the historical RFC 1020 (1987) label "LANL-INET-AS" referred to the same holder then and is retained here only as a historical label. This is one of the rare cases where the famous historical holder persists unchanged. Contrary to the earlier "intermittent" characterization, AS68 is ACTIVE and reliably globally visible: at the 2026-06-19 capture RIPEstat saw 8 IPv4 prefixes originated (~328,448 addresses), including the legacy 204.121.0.0/16 and 128.165.0.0/16 LANL-INET netblocks plus 130.55.0.0/16, 138.98.0.0/16 and 141.111.0.0/16, alongside one IPv6 /40 (2620:126:4000::/40). Visibility is essentially full (IPv4 327/327, IPv6 322/323 RIS peers) and last-seen is today (130.55.0.0/16); upstream is ESnet (AS293), with one observed neighbour. The ARIN ASN RegDate is 1986-04-10 (the LANL-2-Z org RegDate of 2023-11-30 is a registry refresh; the associated 128.165.0.0/16 LANL-INET netblock dates to 1986-09-29). For triage this is a DOE national-lab network, benign, actively routed and reachable via ESnet. No notable public abuse signal was found as of June 2026.
