Summary

Politechnika Bialostocka

Poland · AI-generated

education university poland

The AS handle ASN-BIAMAN-COM is held by Politechnika Bialostocka.

What it's used for

  • The address space carries university infrastructure, evidenced by netnames like PL-BIAMAN-20030801 and reverse DNS entries such as 162.254.biaman.pl and 3lo126.biaman.pl.
  • With 6912 IPv4 addresses across 10 prefixes and 17 observed neighbours, the ratio suggests a typical access network for an educational institution rather than a transit provider.

Notable

  • Registrants consistently identify as Politechnika Bialostocka or BIAMAN Contact Role, aligning with the announcer.
  • The address inventory is finely subdivided into 10 prefixes, including specific allocations like BIAMAN_166 and BIAMAN_WEBSKY, indicating site-by-site segmentation within the university estate.

Classification and threat

Unclassified Not in the curated lists. Most of the ~80,000 allocated ASNs are not.

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 1,768 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.
