Summary

MCX Sp.z o.o.

Poland · AI-generated

business poland small

MCXSYSTEMS-AS is operated by MCX Sp.z o.o.

What it's used for

  • The address space carries corporate infrastructure, evidenced by the netname MCX-NET-PL and reverse DNS entries like hostip-64.mcx.pl and hostip-190.mcx.pl.
  • The AS announces 256 IPv4 addresses across 1 prefix (193.17.203.0/24) and maintains 2 observed neighbours, a ratio consistent with a small business or internal corporate estate rather than a transit or large access provider.

Notable

  • The RDAP registrant MCX Sp.z o.o. matches the registry holder, confirming consistent ownership of the announced space.
  • Secondary sources identify the operator as MCX SERWIS Sp. z o.o., indicating a corporate name variation or historical rename within the same Polish entity.
  • The inventory consists of a single /24 block, representing a compact and self-contained address allocation.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-18, 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: 443 networks and 1,784 prefixes, as published 2026-10-19. 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.
