Summary
Poznan Supercomputing and Networking Center
education research legacy
POZMAN (AS9112) is operated by the Poznan Supercomputing and Networking Center (PSNC / PCSS), affiliated with the Institute of Bioorganic Chemistry of the Polish Academy of Sciences. PSNC runs the POZMAN metropolitan academic network in Poznan.
What it's used for
The AS serves the academic and research community: it announces the large 150.254.0.0/16 legacy academic block plus 62.3.160.0/19 (together ~73k addresses) with a small number of observed neighbours, feeding the Poznan metropolitan network. PSNC is also the operator of Poland's national research and education network PIONIER and a major HPC/e-infrastructure centre, so this space carries university, research-institute and data-centre traffic rather than commercial or subscriber traffic.
Notable
- The
150.254.0.0/16prefix is a classic early academic /16 allocation, announced from this AS since at least 2000. - No PTRs were returned on the addresses sampled.
Interesting
PSNC is one of Europe's larger academic supercomputing centres and coordinates PIONIER, the Polish NREN, giving AS9112 a role well beyond a single campus.

Interconnection

Internet exchanges
No exchange port on file. Many exchanges publish no participant list, so this is not proof of absence.
Transit providers
3 upstream, 1 downstream and 6 adjacent networks observed; most-used upstreams first.
Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-13, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

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: 436 networks and 1,771 prefixes, as published 2026-10-13. 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.
