AS29

AS29 is a legacy single-digit allocation registered under ARIN to Yale University in New Haven, CT, and it remains a live campus network — not MITRE, a common low-number guess (MITRE is AS35, MITRE-AS-1). RFC 1020/1166 label it "YALE-AS — Yale University," the same institution then and now. It originates about five IPv4 prefixes and one IPv6 prefix, roughly 515 /24s of IPv4 and 65,536 /48s of IPv6, with four upstreams and four peers; a PeeringDB record is present (network type "Not Disclosed," RIR status "ok"), and Hurricane Electric flags "AS29 announces bogons," a hygiene note rather than abuse. Current ARIN records show an ASN RegDate of 1984-09-18 (older mirror snapshots show 1984-09-17), and the org record's 2023 date is a refresh. For triage this is a flagship-university network, actively routed, with a clean academic profile. No notable public abuse signal was found as of June 2026.
