About this network

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, registrant TORMAN 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 /17 is 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.
