Summary
Portland State University
education university legacy
PDXNET is the autonomous system of Portland State University, the public research university in downtown Portland, Oregon. It carries the campus network and the university's public-facing services.
What it's used for
- Campus connectivity for students, faculty and staff across PSU's downtown Portland campus.
- Public-facing university services: web, mail, DNS, library and research systems.
- Announces PSU's legacy
131.252.0.0/16block plus a small amount of additional Oregon research-network address space and an IPv6/32.
Notable
The address space is institutional, not commercial. It maps to campus buildings, labs, wired and wireless networks and residence halls rather than to a consumer ISP's subscriber pools, so it behaves like a university network: bursty, weekday-heavy, and dominated by dorm and lab clients rather than households.
The AS is registered under ARIN and dates to the mid-1990s expansion, when individual US universities began taking their own AS numbers instead of sitting behind a regional network.
Interesting
Portland State sits at the centre of Oregon's higher-education networking; the university's routing has long been intertwined with the state's research-and-education network fabric, which is why a small amount of non-131.252 Oregon research space also originates here.

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 1,771 prefixes, as published 2026-10-15. 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.
