AS226

AS226 is Los Nettos, a Los Angeles regional research-and-education network registered under ARIN and administered by USC's Information Technology Services. It is a piece of early Internet history: the regional network was led by Danny Cohen and Jon Postel of USC's Information Sciences Institute (ISI), with founding participants including Charles Seitz (Caltech), Leonard Kleinrock (UCLA), and Richard Kaplan (USC), and the first four nodes — ISI, UCLA, USC, and Caltech — were operational by December 1988, making it one of the first regional networks in Los Angeles. Today it functions as a regional aggregator with roughly 25–28 peers, three upstreams, and about sixteen downstream customer networks (including a children's hospital), connecting members such as Caltech, the Claremont Colleges, JPL, LMU LA, and USC onward via CENIC/Pacific Wave to CalREN, Internet2, ESnet, NASA NREN, and DREN. For triage, encountering AS226 indicates an LA-area research/education or affiliated institutional network behind USC-operated infrastructure; note that USC/ISI's own original ASN is AS4 (ISI-AS), distinct from Los Nettos. No notable public abuse signal was found as of June 2026.
