About this ASN.

Updated  ·  Confidence: High

AS87 is a legacy allocation registered under ARIN to Indiana University (OrgId INDIAN-Z), carrying the handle "INDIANA-AS" — the same label RFC 1020 (1987) recorded, an unbroken institutional holding since the 1986 era. It is Indiana University's campus backbone AS, announcing the 156.56.0.0/16 block (allocated 1991-12-10) among roughly 18 IPv4 and 2 IPv6 prefixes (~655,616 IPv4 addresses), with RPKI mostly valid (18 valid originated, 0 invalid). IU operates major research-networking infrastructure, including the Indiana GigaPOP and I-Light, reflected in its routing point of contact. The ARIN RDAP RegDate is 1986-10-10 (some third-party mirrors show a 0000-00-00 placeholder, which is not a real date — ARIN's date is authoritative). For triage this is a stable, low-abuse research-and-education network, one of the oldest continuously-held university ASNs. No notable public abuse signal was found as of June 2026.
