Summary

LODMAN (Łódź Metropolitan Area Network)

Poland · AI-generated

education research legacy

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.

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: 432 networks and 1,768 prefixes, as published 2026-10-12. 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.
