Summary
ICM, University of Warsaw
education university research legacy
ICM-PUB is held by the University of Warsaw, and is operated by ICM, its Interdisciplinary Centre for Mathematical and Computational Modelling — Poland's main academic supercomputing and data centre.
What it's used for
- Public-facing network services run by ICM: research computing, hosting for scientific portals and digital libraries, and connectivity for partner research institutes.
- About 8,200 IPv4 addresses across six prefixes, mostly in
213.135.0.0/8-era RIPE space plus212.87.16.0/20.
Notable
- Reverse DNS is unambiguous ICM infrastructure:
icm-gw1-…rtr.net.icm.edu.pl,icm-s1-…rtr.core.icm.edu.pl,icm-mx1.rtr.core.icm.edu.pl. Gateway, core router and mail-exchanger names — an institutional network, with no dynamic or subscriber pools anywhere in the sample. - One sampled address in
212.87.16.0/20answershosting.nencki.gov.pl, the Nencki Institute of Experimental Biology. ICM's space carries services for other Polish research institutions, not only the university itself. - Twenty-four observed BGP neighbours — more than a pure leaf campus, reflecting ICM's role as a hosting and peering point for the Polish academic community.

Classification and threat
Education University, school or national research and education network.
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: 431 networks and 1,775 prefixes, as published 2026-10-11. 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.
