Summary
Bryn Mawr College
education legacy
BRYNMAWR is the campus network of Bryn Mawr College, a private liberal arts women's college in Bryn Mawr, Pennsylvania, just outside Philadelphia.
What it's used for
- Campus networking for students, faculty, and staff: academic buildings, residence halls, libraries, and administrative systems.
Notable
- Announces roughly a /16 (about 65,000 IPv4 addresses), which is a generous allocation for a small college and a good example of how early institutional assignments were sized before IPv4 scarcity set in.
- Bryn Mawr is part of a tight consortium with nearby colleges, so some of the network serves shared library and academic resources.

Spamhaus DROP
Not on ASN-DROP The network as a whole is not listed.
No DROP prefixes None of its announced space is on the DROP prefix list.
Spamhaus DROP ("Don't Route Or Peer") lists space and networks run by, or hijacked for, spam and cybercrime operations: 455 networks and 1,849 prefixes, as published 2026-11-14. A short, high-confidence list, so a match is worth taking seriously, and absence from it says little on its own.
FBI IC3
No IC3 indicators Nothing from the FBI IC3 feed.
IC3 threat data is alpha. Absence of an indicator is not evidence of good behaviour, only of absence from this one feed.
