Summary

OARnet

unknown · AI-generated

education network ohio research

The AS handle XAVIER-UNIVERSITY is held by OARnet.

What it's used for

  • The address space carries educational and research traffic, evidenced by reverse DNS entries pointing to xu.edu (Xavier University) and netnames like NETBLK-OARNET and OARNET-CBLK5.
  • With 15,616 IPv4 addresses across 8 prefixes and only 1 observed neighbour, the inventory indicates a large access or eyeball network rather than a transit provider.

Notable

  • All registrants for the announced prefixes are listed as "OARnet; Network Operations Center", which aligns with the operator identity despite the AS handle referencing Xavier University.
  • The address inventory consists of eight distinct IPv4 blocks, including a /20 and several /21s, with no IPv6 prefixes in the inventory.

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 1,784 prefixes, as published 2026-10-19. 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.
