About this network

UCR-EDU is the campus network of the University of California, Riverside, one of the ten campuses of the University of California system.

What it's used for

• The whole of a research university's networking: student residence halls, lecture halls and labs, faculty and staff offices, library systems, and the research computing that a UC campus runs.
• The address space is substantial: two full class-B-sized ranges, 169.235.0.0/16 and 138.23.0.0/16, reflecting an era when large universities were handed generous allocations.

Notable

• An institutional address, not a consumer one: an IP here is a campus device, a lab machine or a dorm connection, so it maps to a place on campus rather than to a household or a hosting customer.
• ARIN's registration for this ASN dates to November 1995, placing UCR among the universities that took their own AS numbers as the academic internet was commercialising.

Interesting

• UC Riverside's two /16s give it roughly 131,000 IPv4 addresses, far more than the campus population. That is typical of universities that were allocated address space before scarcity set in.
