Summary

Fiberhost S.A.

Poland · AI-generated

fiber residential access poland

The AS handle FIBERHOST-ASN is held by Fiberhost S.A.

What it's used for

  • The address space carries residential fiber access traffic, evidenced by reverse DNS entries such as host-79.173.31.255.tesatnet.pl and host-79.173.47.254.tesatnet.pl.
  • The network announces 16384 IPv4 addresses within a single prefix (79.173.0.0/18) and maintains only 1 observed neighbour, a ratio characteristic of an access network rather than a transit provider.
  • Traffic from this AS consists of subscriber eyeballs for a Polish telecommunications operator that builds and operates fiber-optic networks, formerly known as INEA S.A.

Notable

  • The registrant FIBERHOST-RIPE and netname PL-FIBERHOST-20071025 align with the announcer, confirming consistent ownership of the address space.
  • Fiberhost S.A. was formerly known as INEA S.A., a rename that reflects its evolution in the Polish telecommunications market.
  • The inventory consists of a single contiguous IPv4 block with no IPv6 prefixes announced, indicating a focused IPv4-centric deployment.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-16, 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 1,783 prefixes, as published 2026-10-17. 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.
