About this network
LODMAN-AS is the Łódź Metropolitan Area Network, the academic MAN for the city of Łódź, operated by the Lodz University of Technology (Politechnika Łódzka). It is one of the regional MANs that make up Poland's national research and education network alongside PIONIER.
What it's used for
- Around 39,700 addresses across six prefixes — notably 212.191.0.0/17, registered as Metropolitan Area Network LODMAN — plus IPv6 from 2001:b10::/35.
- Reverse DNS splits between the MAN's own infrastructure (e-gw.man.lodz.pl, vrrp-gw.uni.lodz.pl, VPN gateways) and the connected institutions' campuses: pc-212-51-208-NN.p.lodz.pl desktop pools at the technical university, faculty subdomains, and the University of Łódź.
- Connectivity for the city's universities, research institutes and other public institutions, plus the shared academic infrastructure they run.
Notable
- Institutional addressing. A hit here is a campus machine, a lab or an institute in Łódź — not a home connection and not a commercial customer.
- MAN operators like this one are their own kind of animal: a university runs the network, but the address space serves many member institutions across the city, so the specific organisation behind an address varies.
