A low-number legacy university ASN that is genuinely live; traffic from 128.6.0.0/16 should show ordinary campus/research-network behavior. Some mirrors show a 1970-01-01 epoch placeholder on the org record, not a real date.

About this ASN.

Updated  ·  Confidence: High

AS46 is a legacy allocation registered under ARIN to Rutgers, The State University of New Jersey, and it remains a live campus network. It is anchored on the legacy 128.6.0.0/16 Class B block (registered 1985-08-16), and RFC 1166 (July 1990) lists the assignment verbatim as "R 128.6.rrr.rrr RUTGERS," reflecting Rutgers' status as one of the early university members of the NSFNET-era research Internet. As of June 2026 it originates about nine IPv4 prefixes and one IPv6 prefix (~772 /24-equivalents of IPv4), taking transit from Arelion (AS1299), NJEDge.Net (AS21976, the New Jersey regional research/education network), and Hurricane Electric (AS6939), with roughly seven peers; bgp.tools classifies it Eyeball/Academic. The ARIN ASN RegDate of 1985-08-16 matches the historical assignment (some third-party mirrors show a 1970-01-01 epoch placeholder on the org record, which is not a real date). For triage this is a low-number legacy university ASN that is genuinely live; traffic from 128.6.0.0/16 should be expected to show ordinary campus/research-network behavior. No notable public abuse signal was found as of June 2026.
