Summary
University of Wisconsin-Milwaukee
education university research legacy
UW-MILWAUKEE-AS1 is the autonomous system of the University of Wisconsin-Milwaukee, Wisconsin's largest public research university outside Madison.
What it's used for
- Campus networking for UWM: academic departments, research groups, administrative systems, student residences and public-facing university services.
- The AS announces the university's
129.89.0.0/16legacy Class B along with a couple of smaller blocks and an IPv6 prefix.
Notable
- Reverse DNS across the space resolves under
uwm.edu, confirming an institutional campus network rather than a commercial provider. - A Class B allocation plus a low AS number is the standard fingerprint of a US university that connected in the early days of the academic internet, when address space was handed out generously to institutions.

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: 447 networks and 1,852 prefixes, as published 2026-10-27. 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.
