The AS handle PL-INFRATEL-AS is held by Infratel-Operator Infrastrukturalny sp. z o.o.

What it's used for

  • The address space carries infrastructure endpoints, as evidenced by reverse DNS entries such as 156-67-116-64.wss.zgierz.pl, 156-67-116-127.secure-it.com.pl, and 156-67-116-190.infratel.pl.
  • The network announces 256 IPv4 addresses across 1 prefix with 1 observed neighbour, indicating a small, self-contained internal estate rather than a transit or large access network.
  • Traffic from this AS consists of internal corporate infrastructure and web services for the operator's own business operations.

Notable

  • Registrants for the announced prefix 156.67.116.0/24 list both INFRATEL Sp z o.o. Contacts and Infratel-Operator Infrastrukturalny sp. z o.o., aligning with the AS holder.
  • The address inventory consists of a single /24 block, representing a compact and unified corporate network footprint.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-20, 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 1,779 prefixes, as published 2026-10-21. 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.
