education university research legacy

CALPOLY-NET-ENS is the Autonomous System of California Polytechnic State University, San Luis Obispo (Cal Poly), a large public polytechnic in the California State University system.

What it's used for

  • The Cal Poly campus network: student and faculty access, residence halls, academic and research computing, and the university's public services.
  • rDNS across the space is unambiguously campus IT — netadm.calpoly.edu for network administration hosts, its.calpoly.edu for Information Technology Services, ad.calpoly.edu for directory-joined machines.
  • Campus infrastructure services, including public NTP servers (time3.calpoly.edu, time4.calpoly.edu).

Notable

  • The AS announces 129.65.0.0/16, a legacy Class B assigned to the university — the standard allocation for a US campus in the pre-CIDR era.
  • Addresses here are institutional: they belong to campus machines, lab networks and campus Wi-Fi, not to home broadband subscribers. An IP in AS7960 means "someone on the Cal Poly network", which includes students in university housing.

Interesting

  • Cal Poly's "learn by doing" model means a lot of what runs on this network is student-operated — course projects, competition teams and student-run services sit alongside ordinary university IT.

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 1,773 prefixes, as published 2026-10-13. 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.
