Summary
Swarthmore College
education university legacy
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](https://asn.ipinfo.app/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](https://asn.ipinfo.app/AS3778) (Temple University).
