About this network

SWARTHMORE is the ASN of Swarthmore College, a liberal-arts college in Swarthmore, Pennsylvania, southwest of Philadelphia.

What it's used for

• Campus networking: academic departments, administrative systems, the library, computing labs, and student residential networks.
• Announces a legacy /16 — about 65,000 addresses for a college of roughly 1,600 students.

Notable

• Institutional address space serving one campus. Nothing commercial lives here.
• Like its neighbour AS3777 (Haverford College), Swarthmore holds a full /16 — far more address space than a college of its size could ever need, and a direct legacy of classful allocation practice in the early internet.

Interesting

• Swarthmore, Haverford, and Bryn Mawr have long shared a tri-college consortium, so their networks grew up alongside one another. The adjacent AS numbers in the 3770s and 3780s trace the same Pennsylvania cohort, including AS3778 (Temple University).
