Summary
Petrozavodsk State University
education university research legacy
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.ruandwebct20.karelia.ru— university services underkarelia.ru, the regional academic domain PetrSU has long administered. Thewebctname 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.ruservices 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.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-14, 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 1,772 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.
