Summary
Portland Public Schools
education legacy
The network of Portland Public Schools, the K-12 school district serving Portland, Oregon, registered under the handle PPS.
What it's used for
- Networking for district schools and administration: classroom and lab machines, student and staff devices, and the district's own services. The AS announces a single
159.191.0.0/16, a full Class B, for the whole district.
Notable
- This is education space, but K-12 rather than higher education. Addresses here are used by school staff and by students, many of them minors, on district-managed devices behind district filtering.
- A
/16is a generous allocation for a school district, and reflects a mid-1990s ARIN assignment made when addresses were handed out far more freely than they are today.

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.
