Summary
Chuvash State University
education university legacy
CHUVSU — the Chuvash State University named after I. N. Ulyanov, in Cheboksary, the capital of the Chuvash Republic in the Volga region of Russia. The AS carries the university's campus network.
What it's used for
- Campus connectivity. About 1,500 IPv4 addresses in two prefixes, with two BGP neighbours — a small stub academic network.
- rDNS resolves entirely under
chuvsu.ru, and the host names are unusually literal. They encode building, floor, room and occupant:g-205,g-106-2-otdel(department),g-k-206-buh-mat-gr(accounting),b-200-1-23-ESPP-engeneer(an engineer's workstation), and evenii-liftfor a lift controller.
Notable
- Institutional address space, hand-labelled by a network administrator who numbered the campus room by room. Nothing here resembles subscriber or hosting space.
- The registry name is the full legal formulation — "Federal State Educational Institution of higher professional Education" — which is standard for Russian state universities and says nothing beyond that this is a public institution.
Interesting
- The rDNS is effectively a floor plan. Reverse zones like this one are quietly one of the most informative artifacts a university network leaves in public DNS, and they persist for decades because nobody has a reason to clean them up.

Internet exchanges
No exchange port on file. Many exchanges publish no participant list, so this is not proof of absence.
Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-15, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

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 1,781 prefixes, as published 2026-10-16. 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.
