Summary

OARnet (Ohio Academic Resources Network)

United States · AI-generated

education research legacy

OARnet, the Ohio Academic Resources Network (OARNET-AS), a statewide research and education network serving Ohio's universities, schools, and public institutions.

What it's used for

  • Statewide backbone and connectivity for Ohio's higher education, K-12, health care, and government institutions.

Notable

  • A research-and-education network (REN), not a commercial ISP. Part of Ohio's public technology infrastructure.
  • The low AS number reflects an allocation from the internet's earliest years, handed out roughly sequentially.

Classification and threat

Unclassified Not in the curated lists. Most of the ~80,000 allocated ASNs are not.

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.
