About this network

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.
