Summary
Indiana University (IU-RESEARCH)
education university research legacy
IU-RESEARCH is Indiana University's research-dedicated autonomous system, distinct from the university's general campus network. It is a small, purpose-built AS: RIS sees 5 announced IPv4 prefixes covering roughly 10,240 addresses, plus a single IPv6 prefix.
What it's used for
The routing evidence points squarely at science networking rather than campus IT. The announced space sits in 149.165.0.0/16, and sampled reverse DNS resolves into iu.edu hosts alongside names under jetstream-cloud.org — Jetstream, the NSF-funded research cloud that Indiana University operates for the national academic community. Names such as iut2-... are consistent with the ATLAS Midwest Tier-2 grid computing presence IU hosts. This is a network carrying research compute, data movement, and cloud workloads for scientists, not dormitory or office traffic.
Notable
RIS observes only a single BGP neighbour for this AS. That is the signature of a stub network hanging off one upstream — here, almost certainly Indiana University's own primary AS and the regional/national research backbone behind it — and it firmly rules out any transit or wholesale role despite the university's substantial size. The AS exists to give research traffic its own routing identity and policy, a common pattern for Science DMZ deployments that need to bypass the enterprise firewall path.
Interesting
Indiana University has long been unusually deep in national research networking infrastructure, operating network operations centers and major NSF cyberinfrastructure. A separate ASN for the research arm is a deliberate architectural choice, not an accident of history.

Interconnection
Peering at a glance
Internet exchanges
No exchange port on file. Many exchanges publish no participant list, so this is not proof of absence.
Transit providers
1 upstream, 0 downstream and 2 adjacent networks observed; most-used upstreams first.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-31, 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: 447 networks and 1,845 prefixes, as published 2026-10-31. 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.
