Summary
Perm National Research Polytechnic University (PNRPU)
education university research legacy
PSTU-AS is the campus network of Perm National Research Polytechnic University (formerly Perm State Technical University) in Perm, Russia.
What it's used for
- Campus, teaching, and research networking for the university's faculties and computer-communication centre.
- Reverse DNS across the announced space resolves under
pstu.ruandpstu.ac.ru, including gateway and nameserver hosts, so the address space is used directly by the institution rather than resold.
Notable
- The registered contacts sit in the university's own Computer Communications Laboratory and Computer Communication Centre in Perm, which is typical of a university that runs its own network operations in-house.
- Address space is modest for a university of its size: roughly a /20 plus a small legacy assignment, all announced under this single ASN.
Interesting
- The name change from "Perm State Technical University" to "Perm National Research Polytechnic University" is still visible in the registry: the ASN handle and several contact records use the older name, while the organisation record uses the current one.

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: 453 networks and 1,846 prefixes, as published 2026-11-12. 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.
