Education ARIN
Summary
OARnet (Ohio Academic Resources Network)
education research legacy
OARNET-AS-1 belongs to OARnet, Ohio's statewide research and education network, which connects universities, colleges, K-12 districts, hospitals, and state and local government across Ohio.
What it's used for
- Historically an OARnet routing ASN. It is not currently announcing any prefixes, so its registered address count reflects space held rather than a live routed footprint. OARnet's production traffic rides its other autonomous systems.
Notable
- A regional research and education network (an REN), so its address space is institutional: campuses, labs, and public-sector sites, not homes or hosting tenants.
- ARIN's registration dates to 1993, placing OARnet among the state-level academic networks that were the backbone of US internet access before commercial ISPs took over that role.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-15, 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 1,782 prefixes, as published 2026-10-16. 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.
