About this network

The campus network of The Pennsylvania State University (PENN-STATE), the public land-grant research university headquartered at University Park, Pennsylvania.

What it's used for

• Campus, residential, academic, and administrative networking for Penn State — not just University Park but the university's many Commonwealth Campuses spread across the state.
• Research networking, including connectivity for a large R1 research enterprise and its supercomputing and data resources.

Notable

• One of the larger university networks by address count, with well over 400,000 IPv4 addresses behind it — a scale reached by very few institutions and a sign of a legacy allocation from the era when universities received generous blocks.
• Institutional address space: users behind it are students, faculty, staff, and research systems rather than broadband subscribers or hosting customers.

Interesting

• Penn State's four-digit AS number and its outsized IPv4 footprint both reflect how central American research universities were to building out the early internet.
