Summary

FAN-TEX

Poland · AI-generated

business poland small

The AS handle FAN-TEX-AS is held by "FAN-TEX" Aleksander Grzegorz HIRSZTRITT.

What it's used for

  • The address space carries business and network infrastructure traffic, evidenced by reverse DNS entries such as ipa128.nex.el.fantex.net and ipb126.nex.el.fantex.net, alongside standard host records like 176-109-130-0-fan-tex.pl.
  • The network announces 5,632 IPv4 addresses across 4 prefixes, with only 2 observed routing neighbours, indicating a small, self-contained business network rather than a transit or large-scale access provider.
  • Traffic from this AS consists of internal corporate endpoints and network infrastructure for the operator's business operations in Poland.

Notable

  • All four announced prefixes share the netname FAN-TEX and are registered to "FAN-TEX" Aleksander Grzegorz HIRSZTRITT, confirming consistent ownership and alignment with the AS holder.
  • The address inventory is compact, consisting of four distinct IPv4 blocks in Poland 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 2026-11-12, 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: 453 networks and 1,848 prefixes, as published 2026-11-12. 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.
