Summary
NETCOM Computers
residential isp regional cable
NETCOM is operated by NETCOM Computers, a regional internet service provider based in Kalisz, Poland.
What it's used for
- The address space carries residential broadband traffic, evidenced by reverse DNS entries such as
255.pool-41.szybki-internet.euand254.pool-42.szybki-internet.eu, which reference the operator's "szybki-internet" (fast internet) service. - The AS announces 1536 IPv4 addresses across 2 prefixes (
185.155.40.0/22and91.231.74.0/23) while maintaining 8 observed neighbours, a ratio consistent with an access network providing last-mile connectivity rather than transit. - Traffic from this AS consists of subscriber eyeballs accessing the internet via cable or DSL connections in the Kalisz region, as indicated by the operator's classification as a Cable/DSL/ISP.
Notable
- Registrant data for both announced prefixes (
PL-NETCOM2-20160607andPL-NETCOM2) aligns with the AS holder, Robert Jerzy Opielinski trading as NETCOM COMPUTERS. - The address inventory is compact, consisting of two contiguous blocks in Poland, with no IPv6 prefixes currently announced.

No exchange port on file. Many exchanges publish no participant list, so this is not proof of absence.
Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-30, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

Classification and threat
Residential Fixed-line consumer ISP. Addresses here are homes.
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: 448 networks and 1,849 prefixes, as published 2026-10-30. 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.
