AS79

AS79 is a legacy allocation registered under ARIN to Los Alamos National Laboratory, carrying the handle "DSPO-HC-AS." RFC 1020 (1987) labeled it "DSPO-HC-AS," and it has been consistently associated with LANL — a U.S. Department of Energy / NNSA national laboratory and FFRDC. This is a second, largely dormant LANL legacy number: LANL's primary operational network is the separate AS68 (LANL-INET-AS), and AS79 shows no confirmed live prefix origination as of June 2026. The ARIN RDAP RegDate is 1986-05-05. For triage, treat AS79 as a DOE/FFRDC institutional allocation; live LANL traffic is AS68, not AS79. No notable public abuse signal was found as of June 2026.
