Unclassified RIPE
Summary
TORMAN
education university nren
A Polish city's academic network, run out of the university that operates it.
What it's used for
- Academic and research connectivity for Torun. 32,768 addresses in a single
/17,158.75.0.0/17, plus one IPv6/32, with two observed BGP neighbours.
Notable
- The holder is Nicolaus Copernicus University in Torun; the AS handle reads
TORMAN-EDU Torun Regional Computer Network. - The one IPv4 block is netname
TORMAN-EDU, registrantTORMAN NOC— the network operations centre is listed rather than the university. - One prefix, one IPv6
/32, two neighbours. Nothing here is deaggregated.
Interesting
- Poland built its academic networking as a set of city networks — a MAN in each university town, each run by one local institution on behalf of all of them, and all of them joined by a national backbone. TORMAN is Torun's. The naming holds the arrangement together: the AS is a city network, the registrant is its NOC, and the legal holder is the university that houses both.
- A
/17is half a former class B, and university networks across Europe hold blocks of exactly this shape from the era when address space was requested by letter and granted by size of institution.

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.
Transit providers
2 upstream, 0 downstream and 2 adjacent networks observed; most-used upstreams first.
Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-12, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

Classification and threat
Unclassified Not in the curated lists. Most of the ~80,000 allocated ASNs are not.
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: 436 networks and 1,769 prefixes, as published 2026-10-13. 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.
