Summary

KOLNET

Poland · AI-generated

residential isp poland access

KOLNET is operated by KOLNET Sp. z o.o.

What it's used for

  • The address space carries static residential or business customer endpoints, evidenced by reverse DNS entries such as klient-88-135-164-0.static.kolnet.eu and klient-95-215-194-0.static.lupro.net.
  • The AS announces 8192 IPv4 addresses across 3 prefixes and maintains 2 observed neighbours, a ratio characteristic of an access network providing last-mile connectivity rather than transit.
  • Traffic consists of subscriber eyeballs and static IP services for end-users in the Czechowice-Dziedzice region of Poland.

Notable

  • Registrants align with the announcer for the KOLNETSC netnames, while the LUPRO-NET prefix is registered to LUPRO Sp. z o.o., indicating a separate entity or historical acquisition within the same AS.
  • The inventory is composed of three distinct IPv4 blocks: 88.135.160.0/20, 95.215.192.0/21, and 213.5.248.0/21, with no IPv6 prefixes announced.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-15, 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: 442 networks and 1,781 prefixes, as published 2026-10-16. 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.
