Summary
Kuban State University
education university research legacy
KUBANNET is the campus network of Kuban State University (Kubanskiy Gosudarstvennyy Universitet) in Krasnodar, southern Russia, a federal state-funded institution of higher education.
What it's used for
- University campus connectivity: faculties, labs, libraries and student facilities in Krasnodar, plus the regional academic network the university anchors.
- Roughly 4,300 IPv4 addresses across four prefixes, concentrated in
212.192.128.0/20with one further /24.
Notable
- Reverse DNS is sparse: most sampled addresses answer with the address itself, and the one named host is
cs-kubsu.kubannet.ru— thekubsulabel being the university's own abbreviation. No dynamic, DSL or PPPoE naming appears anywhere in the sample, which is what a campus network rather than a consumer ISP looks like. - Only two observed BGP neighbours. This is a leaf network buying transit, not a carrier: it originates its own space and provides transit to nobody.
- The
212.192.128.0/19prefix has been visible in the routing table since at least 2000, consistent with an early Russian academic allocation.

Interconnection
Peering at a glance
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 2026-10-18, 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: 443 networks and 1,784 prefixes, as published 2026-10-19. 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.
