About this network

MARIST is the campus network of Marist University in Poughkeepsie, New York, known as Marist College until it took university status in January 2025.

What it's used for

• Campus networking for a private university: residence halls, classrooms and labs, faculty and staff systems, administration, and Marist's unusually large research-computing estate.
• It announces a single class-B-sized block, 148.100.0.0/16, giving it around 65,000 IPv4 addresses for the campus.

Notable

• An institutional address: an IP here is a campus machine, a lab system or a student connection, not a household and not a hosting customer.
• ARIN's registration for the ASN dates to November 1995, so the campus has run its own autonomous system since the mid-1990s.

Interesting

• Marist sits a few miles from IBM's Poughkeepsie mainframe plant, and the two have run a joint study partnership for decades, starting with an IBM 3090 installed on campus and continuing through current-generation z-series hardware. It has made a mid-sized liberal-arts university into a serious mainframe and Linux-on-Z research site, which is not what a /16 in Poughkeepsie would otherwise suggest.
