About this network

The Lublin metropolitan academic network, operated by Maria Curie-Skłodowska University.

What it's used for

• Connecting universities, schools and public institutions across the city of Lublin. 16,896 addresses over eighteen prefixes, with six observed BGP neighbours.

Notable

• Reverse DNS is built in three parts: site, interface, then aggregation device. Names such as witosa3.eth0.smartbox-14499.lubman.net.pl and hirszfelda3.vlan417.shrike.lubman.net.pl give the connected building, the port it lands on and the box it lands in.
• The site labels are street names and institution abbreviations — witosa3, hirszfelda3, zso1, witd, ekohome — which reads as a network wired building by building rather than subscriber by subscriber.
• Addresses not in service answer with a leading UNUSED. label.
• Two legacy /24s, 192.188.233.0/24 and 192.188.235.0/24, are registered directly to the university under the netnames LUBLIN and LUBMAN. The rest sit under PL-UMCS-LUBMAN-LSP-1 and -LSP-2.

Interesting

• Poland built its academic internet as a set of city networks — MANs — each run by a local university and each serving far more than that university. LUBMAN is Lublin's, and the reverse DNS shows the consequence: schools and public offices on the same network as the campus, addressed by their street.
• The university is named for the physicist born Maria Skłodowska in Warsaw, who did her work in Paris under the name most of the world knows. The Polish name comes first here.
