About this network

PETRSU-AS belongs to Petrozavodsk State University (PetrSU), the largest university in the Republic of Karelia, in Russia's north-west near the Finnish border.

What it's used for

The campus network. It is a small AS by design — about 1,280 IPv4 addresses across four prefixes — and the reverse DNS is entirely first-party academic:

• ip195-209-248-100.petrsu.ru — sequentially named campus addresses in the university's own zone.
• iias.karelia.ru and webct20.karelia.ru — university services under karelia.ru, the regional academic domain PetrSU has long administered. The webct name is a survivor of the WebCT era of virtual learning environments.
• runnet-tunnel.petrsu.ru — a link into RUNNet, the Russian federal university network, which is the university's academic transit.

Notable

• A single observed BGP neighbour, consistent with an institution that reaches the internet purely through the national research and education network rather than buying commercial transit.
• PetrSU has historically been a significant regional hub for academic networking in Karelia, providing connectivity and hosting for other Petrozavodsk institutions, which is why karelia.ru services live inside its address space.

Interesting

The runnet-tunnel hostname is a small piece of network archaeology: it names a tunnel rather than a native circuit, a common way regional Russian universities were originally grafted onto the federal RUNNet backbone.
