About this network

The campus network of Stony Brook University, a flagship research campus of the State University of New York on Long Island, under the handle SUNYSB.

What it's used for

• Connectivity for the university's colleges, residence halls, research groups and medical centre, on legacy class-B space (129.49.0.0/16 and 130.245.0.0/16) plus modern IPv6 allocations.
• Supports research computing and data-intensive science, the usual load for a major public research university.

Notable

• Institutional address space, serving students, faculty and university systems rather than paying subscribers.
• Dual class-B allocations plus several early 192.12.x /24s mark this as an early-connected campus that accumulated address space before allocations tightened.
