About this network

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 212.192.128.0/20 with 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 — the kubsu label 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 212.192.128.0/19 prefix has been visible in the routing table since at least 2000, consistent with an early Russian academic allocation.
