Summary
BIAMAN (Białystok Academic MAN)
education research university legacy
BIAMAN (ASN-BIAMAN-EDU) — the Białystok metropolitan academic network, operated by Politechnika Białostocka (Białystok University of Technology). The handle's MSK is miejska sieć komputerowa, Polish for "city computer network".
What it's used for
- Campus and inter-institutional connectivity for the universities, colleges and research institutes of Białystok and the surrounding Podlaskie region. The rDNS lands squarely on academic hosts —
aragorn.wb.pb.edu.pl(the university's own faculty machines),www.al.edu.pl, and the network's operational infrastructure atdns.man.bialystok.pl. - Beyond the campuses it also serves regional public bodies: one sampled host is
wms1.wios.bialystok.pl, the provincial environmental-protection inspectorate. Polish MANs traditionally carry local government and cultural institutions alongside their academic members.
Notable
- This is one of the roughly twenty Polish metropolitan area networks that together form the national academic backbone, PIONIER. Each MAN is run by a local host institution — here the technical university — rather than by a separate corporate entity, which is why the AS is registered to the Politechnika itself.
- Institutional address space: around 22,000 IPv4 addresses in a handful of
large blocks (82.139.128.0/19, 212.33.64.0/19). There are no subscriber pools and only a small number of BGP neighbours, as befits a network whose upstream is the national research backbone rather than the commercial market.

Internet exchanges
No exchange port on file. Many exchanges publish no participant list, so this is not proof of absence.
Transit providers
3 upstream, 2 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 2026-10-10, 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: 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.
