Summary

LUBMAN (Maria Curie-Skłodowska University)

Poland · AI-generated

university education research legacy

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.

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: 442 networks and 1,783 prefixes, as published 2026-10-17. 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.
