About this network

ORST-AS is Oregon State University, the land-grant research university in Corvallis, Oregon.

What it's used for

• Campus networking for students, faculty, and staff: instruction, research computing, libraries, residence halls, and administrative systems.
• Supporting OSU's research programs, which span agriculture, forestry, oceanography, and engineering, along with its statewide Extension presence.

Notable

• This is institutional address space, so traffic from it is campus users rather than commercial subscribers.
• The allocation is large for one university (roughly 65,000 addresses), typical of schools that received IPv4 space early.

Interesting

• Oregon State has a long-running association with open-source infrastructure through the OSU Open Source Lab, which has hosted mirrors and project infrastructure for major free-software communities.
