Summary

University of Puerto Rico

Puerto Rico · AI-generated

education university research legacy

UPRENET is the network of the University of Puerto Rico, the island's public university system. It is the academic network serving UPR's campuses.

What it's used for

  • Campus networking across the UPR system: teaching, administration, student residences and research computing.

Notable

  • An institutional academic network, not a commercial provider. An IP here is a university campus, so it may be a lab machine, a staff desktop or student wireless rather than a hosted server.
  • The system holds a full legacy /16 at 136.145.0.0, announced as roughly 200 separate prefixes. That heavy deaggregation is characteristic of a multi-campus university carving its space up per site and department.

Interesting

  • The low AS number and the classful /16 both reflect an early allocation, from the era when a large university could be handed a whole Class B block.

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: 431 networks and 1,775 prefixes, as published 2026-10-11. 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.
