AS17 is a legacy single-digit allocation registered under ARIN to Purdue University, and it is a clean, fully RPKI-valid academic network — a model of good routing hygiene in this cohort. It announces the historic 128.10.0.0/16, 128.46.0.0/16, 128.210.0.0/16, and 128.211.0.0/16 blocks plus IPv6 (2607:ac80::/32, 2001:18e8:800::/44) — about nine IPv4 prefixes and three IPv6 prefixes, ~262,912 IPv4 addresses — and all twelve announcements are RPKI-valid with zero invalid. Observed peering/upstream is via Indiana University (AS19782) and Wintek Corporation (AS11114), and the RADB object is maintained by Indiana University's GlobalNOC. The ARIN ASN RegDate of 1984-08-01 is the registry date (Purdue's first IP block, 192.5.48.0/24 PURDUE-CS-NET, dates to December 1983). For triage this is a benign, well-run university network routed via Indiana University's GlobalNOC. No notable public abuse signal was found as of June 2026.
