About this ASN.

Updated  ·  Confidence: High

AS88 is a legacy allocation registered under ARIN to Princeton University (OrgId PRNU-Z), carrying the handle "PRINCETON-AS" — the same label RFC 1020 (1987) recorded, held continuously since the 1986 era. Princeton's OIT Network Switching and Routing operates this AS for the campus, announcing IPv4 and IPv6 prefixes (about 137,472 IPv4 addresses observed) and exporting AS88:AS-ALL, with roughly three BGP peers observed. The ARIN ASN RegDate is 1986-10-10 (the aut-num object was recreated 2021-09-16, a registry refresh). For triage this is a mainstream university backbone, clean and actively announcing. No notable public abuse signal was found as of June 2026.
