Summary

Technical University of Koszalin

Poland · AI-generated

education university poland

KOSMAN-EDU-AS is operated by Technical University of Koszalin.

What it's used for

  • The address space carries university infrastructure, evidenced by reverse DNS entries such as 164-0.IHAR.man.koszalin.pl and host254.181.tu.koszalin.pl, alongside netnames like PL-KOSMAN-20021204 and PL-KOSMAN-20110310.
  • The AS announces 8192 IPv4 addresses across 3 prefixes and 1 IPv6 prefix, with only 2 observed neighbours, indicating a small, self-contained educational network rather than a transit provider.

Notable

  • Registrants consistently identify the Technical University of Koszalin and its NOC, aligning perfectly with the AS handle and registry holder.
  • The inventory consists of three IPv4 blocks (62.108.160.0/20, 31.25.248.0/21, 62.108.176.0/21) and one IPv6 prefix (2001:4c70::/32), all located in Poland.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-27, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

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: 447 networks and 1,852 prefixes, as published 2026-10-27. 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.
