Summary

Perm State National Research University

Russia · AI-generated

education university research legacy

Perm State National Research University (PSU-AS) — the classical university of Perm, in the Russian Urals, founded in 1916 and one of the institutions granted "national research university" status. The AS carries the campus network behind psu.ru.

What it's used for

  • Campus connectivity: about 4,350 IPv4 addresses across a small, contiguous 212.192.64.0/20 allocation, plus one IPv6 /48. rDNS is entirely first-party psu.ru — building networks (Korp5-NET.psu.ru, i.e. korpus, a campus block), gateway routers (gw-net64.psu.ru), named servers, and a legacy Dialup-NET.psu.ru / dialup-gw.psu.ru remnant of modem-era access.
  • Faculty and student services, university-hosted servers, and research groups. There is no subscriber, hosting or commercial-customer naming anywhere in the space.

Notable

  • A small, single-purpose institutional network: three BGP neighbours, one contiguous block, no downstreams. That is the classic profile of a university AS that buys transit and announces only its own campus.
  • The addresses should be read as institutional — offices, labs, lecture halls, halls of residence — not as consumer eyeball space, even though student traffic flows through them.

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.
