Network type: education

About this network

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.
