AS12324 LUBMAN-EDU-AS Poland, Lublin

LUBMAN is the academic network of Lublin, run by Maria Curie-Skłodowska University and serving the city's institutions rather than just its own campus.

What it's used for

• Metropolitan academic networking. Reverse DNS runs under lubman.net.pl, and the names that answer are router interfaces — am.lt1-0-0x788.nucky.lubman.net.pl and 2lo.vlan110.nemes.lubman.net.pl, naming the box, the interface and the VLAN.

Notable

• 66,816 addresses over seven prefixes, with ten observed BGP neighbours. That is a great deal more address space than a single university needs, and the ten neighbours are the other half of the picture: this network carries other people's traffic.
• The netnames date the growth across sixteen years — PL-UMCS-990303 in March 1999, then PL-UMCS-20050905, PL-UMCS-20120829 and PL-UMCS-20141107.
• Registry contacts are split into four roles: administrators, operators, the university itself, and a separate abuse-handling contact. No IPv6 announced.

Interesting

• Poland built its academic networking as a set of metropolitan area networks, each run by a local university on behalf of every research institution in its city, rather than as one national provider reaching each campus directly. LUBMAN is Lublin's. The arrangement is why a university AS here holds a /17 and peers with ten networks.
• The university is named for Maria Skłodowska-Curie, who was born in Warsaw and is still the only person to have won Nobel Prizes in two different sciences. The Lublin university took her name in 1944, ten years after her death.
