AS8664 — ICM-PUB public network services

Network type: education

AS8664 announces 6 IPv4 prefixes covering 8,192 addresses and 1 IPv6 prefixes.

About this network

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 plus 212.87.16.0/20.

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 212.87.16.0/20 answers hosting.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.
