About this network

UCSC is the University of California, Santa Cruz, a public research university on California's central coast and a campus of the University of California system.

What it's used for

• Campus networking for UCSC: student and staff devices, residential halls, labs, libraries and administrative systems, plus the university's public-facing web and research services.

Notable

• An institutional network rather than a commercial one. Addresses here belong to a single campus community, so they cluster tightly in Santa Cruz County.
• UCSC's ARIN organisation record dates back to 1986 and the ASN to 1995, consistent with a university that was on the internet well before the commercial era.

Interesting

• UCSC hosts the Genomics Institute, whose UCSC Genome Browser is one of the most widely used public resources in biology, so a meaningful share of this network's outbound traffic is scientific data rather than campus browsing.
