Summary

Santa Clara University

United States of America · AI-generated

education university business

The AS handle SCU-ASN is held by Santa Clara University.

What it's used for

  • The address space carries university infrastructure, evidenced by the consistent netname SCU-NET across the primary inventory.
  • The AS announces 65,544 IPv4 addresses across 10 prefixes, with only 3 observed neighbours, indicating an internal campus network rather than a transit provider.

Notable

  • Registrants align with the announcer for the majority of the space, with Santa Clara University listed for all 129.210.0.0 blocks.
  • The smallest prefix, 204.102.225.32/29, is registered to CENIC, a different organization from the primary holder.
  • The inventory is dominated by the 129.210.0.0 range, which is finely subdivided into multiple prefixes of varying sizes.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-14, 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 1,772 prefixes, as published 2026-10-15. 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.
