Summary

Stevenson University

United States of America · AI-generated

education business university

The AS handle SU-ASN-1 is held by Stevenson University.

What it's used for

  • The address space carries the university's internal network, identified by the netname SU-NETWORK-01 and registrant Stevenson University.
  • The inventory consists of 1024 IPv4 addresses within the single prefix 64.89.164.0/22 and one IPv6 prefix 2602:faba::/36. With only 3 observed neighbours, the low address-to-neighbour ratio indicates a small, self-contained institutional network rather than a transit or large-scale access provider.

Notable

  • The RDAP registrant for the announced prefix matches the AS holder, confirming the space is owned and operated by the university.
  • Stevenson University was founded in 1947 as Villa Julie College and adopted its current name in 2008.
  • The address inventory is compact, consisting of a single /22 block and a /36 IPv6 prefix, typical for a mid-sized higher education institution.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-19, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

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 1,783 prefixes, as published 2026-10-20. 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.
