Summary
State University of New York at Buffalo
education university research legacy
BUFFALO-ASN is the campus network of the University at Buffalo (SUNY Buffalo), the largest campus in the State University of New York system.
What it's used for
- Campus, research, and administrative networking across UB's North, South, and downtown campuses.
- Research and high-performance computing connectivity for the university's science, engineering, and medical programs.
Notable
- Institutional address space: labs, lecture halls, offices, campus Wi-Fi, and residence halls, not commercial subscribers.
- The footprint is large for a single university, reflecting a decades-old allocation made when campuses assigned public addresses freely rather than hiding behind NAT.
Interesting
- The low AS number reflects UB's early presence on the research internet, a period when US universities held a disproportionate share of the routing table.

Internet exchanges
No exchange port on file. Many exchanges publish no participant list, so this is not proof of absence.
Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-21, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

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: 442 networks and 1,779 prefixes, as published 2026-10-22. 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.
