Summary
Stephen F. Austin State University
education university legacy
The campus network of Stephen F. Austin State University (SFASU-AS), a public university in Nacogdoches, Texas.
What it's used for
- Campus networking for students, faculty, and staff: academic buildings, labs, residence halls, libraries, and administrative systems.
- Announcing the university's own address space, a sizeable legacy allocation of the kind commonly held by 1990s university registrants.
Notable
- Institutional address space. Traffic from this ASN is a university community — a mix of academic, administrative, and campus-residential use.
- SFASU joined the University of Texas System, becoming part of a much larger public system while keeping its own campus network identity.
Interesting
- Universities were among the earliest organisations to run their own autonomous systems, which is why so many of them cluster in the low AS ranges.

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: 443 networks and 1,779 prefixes, as published 2026-10-24. 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.
