Summary
Illinois State University
education university legacy
The campus network of Illinois State University in Normal, Illinois (ILLINOIS-STATE-UNIV), an early ARIN-registered ASN dating to 1996.
What it's used for
- Campus, academic, and administrative networking for Illinois State University.
- Announces a single legacy
138.87.0.0/16— a full Class B assigned to the university, which is more than enough address space for a campus of its size.
Notable
- Institutional address space, not consumer broadband: expect student housing, labs, lecture halls, library systems, and university-run servers rather than residential subscribers.
- Registered to Administrative Technologies at Campus Box 3380 — the central IT organisation that runs the university's networking.
Interesting
- The university keeps its entire routed footprint inside one /16 with no IPv6 announced at the ASN level, a fairly conservative posture for a large public university.

Internet exchanges
No exchange port on file. Many exchanges publish no participant list, so this is not proof of absence.
Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-16, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

Spamhaus DROP
Not on ASN-DROP The network as a whole is not listed.
No DROP prefixes None of its announced space is on the DROP prefix list.
Spamhaus DROP ("Don't Route Or Peer") lists space and networks run by, or hijacked for, spam and cybercrime operations: 442 networks and 1,783 prefixes, as published 2026-10-17. A short, high-confidence list, so a match is worth taking seriously, and absence from it says little on its own.
FBI IC3
No IC3 indicators Nothing from the FBI IC3 feed.
IC3 threat data is alpha. Absence of an indicator is not evidence of good behaviour, only of absence from this one feed.
