Summary

Oberlin College

United States of America · AI-generated

education business residential

OBERLIN-COLLEGE is operated by Oberlin College.

What it's used for

  • The address space carries the college's internal network, with netnames OBERLIN and registrants listed as Oberlin College; Network Operations Center.
  • The AS announces 65792 IPv4 addresses across 4 prefixes, maintaining only 2 observed neighbours, a ratio indicative of a self-contained institutional network rather than a transit provider.

Notable

  • Registrants for the three largest prefixes align with the announcer, while the smallest prefix 199.18.94.0/24 is registered to OARnet; Network Operations Center under the netname NETBLK-OARNET-CBLK2.
  • The inventory consists of three large blocks within the 132.162.0.0/17 range and one smaller /24 block, reflecting a standard allocation for a mid-sized educational institution.

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.
