Summary

TELBIAL

Poland · AI-generated

business construction poland

The AS handle TELBIAL-AS is held by Zaklad Budownictwa Liniowego TELBIAL Sp z o.o.

What it's used for

  • The address space carries corporate infrastructure for a linear construction company, with reverse DNS pointing to net.hawetelekom.pl and netnames TELB-0234 and PL-APMEDIA-20171219.
  • The network announces 1024 IPv4 addresses across 3 prefixes with only 1 observed neighbour, indicating a small, isolated internal corporate estate rather than a transit or access provider.
  • Traffic from this AS consists of office workers and internal systems for a construction firm, not subscriber eyeballs or public web endpoints.

Notable

  • Registrants include AP-MEDIA Spolka z ograniczona odpowiedzialnoscia for the 185.237.160.0/23 block and HAWE-ADMIN for the 78.159.82.0/24 and 78.159.87.0/24 blocks, suggesting leased or historically allocated space rather than a single unified corporate allocation.
  • The inventory is small and finely subdivided into three distinct /24 and /23 blocks, consistent with site-by-site segmentation for a business operator.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-26, 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 1,779 prefixes, as published 2026-10-24. 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.
